 - Fix path-with-spaces bug reported by Eleanor Murray on Discourse
   - https://geant4-forum.web.cern.ch/t/problem-running-example-b1/451
   - Triaged as the include paths not being quoted so that when they have

 7th September 2017 - Ben Morgan (cmake-V10-03-34)
 - Modules/G4DeveloperAPI_OLD.cmake: Set INSTALL_RPATH on macOS
   Requested by Fons Rademackers. Loading Geant4 dylibs in Python
   can lead to resolution errors as they cannot locate each other.
   Append "@loader_path" to the INSTALL_RPATH for all Geant4 libraries.
   This will expand to the directory of the library being loaded, which
   will contain the other Geant4 libraries. Append is used to that
   users may still supply CMAKE_INSTALL_RPATH at configure time,
   and this will be preferred.
 
 5th September 2017 - Gunter Folger (cmake-V10-03-33)

 - Create a G4HDF INTERFACE target for uniform access to HDF5 headers
   and libraries at build, test and install time. It is not completely
   relocatable as the target hardcodes header/library paths. However,
   it creates a single point of access so that adding relocation
   will require minimal changes, limited to the cmake category.
 
 27th July 2017 - Ivana Hrivnacova (cmake-V10-03-30)
 - Removed FindHdf5.cmake as the find module is provided with CMake
 
 27th July 2017 - Ivana Hrivnacova (cmake-V10-03-29)

   as ROOT's CMake functions do not support usage requirements
   or generator expressions yet.
 
 21st February 2017 - Gunter Folger  (cmake-V10-03-10)
  base on tag cmake-V10-03-06, and only update History
  and Modules/Geant4DatasetDefinitions.cmake to trunk.
  Changes to above two files committed first in trunk.
  Then create branch cmake-V10-03-06_branch for tagging.

 - switch to PhotonEvaporation 4.3.2
 
 10th February 2017 - Ben Morgan (cmake-V10-03-08)
 - Bugfix: Continuous identified issue on Windows and internal CLHEP.
   Way that DLLs are built means that target_include_directories are
   not propagated to intermediate archive library, causing builds
   to fail due to missing CLHEP headers.
 - Geant4OptionalComponents.cmake : Set CLHEP_INCLUDE_DIRS to internal
   path for CLHEP headers with using builtin CLHEP.
 - TODO: look at resolution via better DLL build process.
 
 9th February 2017 - Ben Morgan (cmake-V10-03-07)

 8th February 2017 - Ben Morgan (branch cmake-bugfix-1934)
 - BUGFIX 1934
 - Note that this patch should not be applied to Geant4 < 10.3 without additional
   changes to support CLHEP's imported targets in versions =< 2.3.3.0.
 - See the comments in Geant4OptionalComponents.cmake for details.
 - Remove obsolete FindCLHEP.cmake module
 - Geant4OptionalComponents.cmake: Update Internal/System CLHEP selection
   - Prepend CLHEP_ROOT_DIR to CMAKE_PREFIX_PATH so that find_package's
     Config mode finds CLHEP as FindCLHEP did. Retain auto-activation
     of GEANT4_USE_SYSTEM_CLHEP if CLHEP_ROOT_DIR supplied.
   - Simplify System/Granular CLHEP selection using dependent options
   - Simplify location/setup of system CLHEP as CLHEP >= 2.3.3.0 provides
     CLHEP_LIBRARIES set with appropriate single/granular targets with
     full usage requirements.
   - Remove setting of GEANT4_USE_BUILTIN_CLHEP variable.
 - G4ConfigureCMakeHelpers.cmake: Remove install of deleted FindCLHEP module

   G4DeveloperAPI_OLD.cmake.
 - Leave Geant4MacroDefineModule and Geant4MacroLibraryTargets modules
   as stubs which simply forward to G4DeveloperAPI. At present these modules
   are included in several places, so maintaining their presence is required.

 - switch to G4EMLOW 6.50
 
 6th October 2016 - Ben Morgan (cmake-V10-02-26)
 - Modules/Geant4MakeRules_cxx.cmake : Move all -f optimization options
 to Release mode only. Add -fno-math-errno and -ftree-vectorize.
 
 
 6th October 2016 - Ben Morgan (cmake-V10-02-25)
 - Modules/Geant4MakeRules_cxx.cmake : Add -fno-trapping-math to default
 flags of GCC/Clang compielrs to assist in auto-vectorization (recommended
 by CMS/GCC). Bump optimization level in Release mode to O3 on all supported
 compilers.
 
 3rd October 2016- Gunter Folger (cmake-V10-02-24)
 - switch to use G4ENSDFSTATE 2.0
   (requires tag particles-V10-02-28)
 
 29th September 2016 - Robert Hatcher (cmake-V10-02-23)
 - Templates/Geant4Config.cmake.in : No longer use --whole-archive for
 G4physicslists on static builds; this was never possible for _WIN32 and recent
 physics list factory work makes this untenable on some build platforms.
 
 28th September 2016 - Andrea Dotti  (cmake-V10-02-22)
 - add option for TEXT output file in FindStatTest.cmake script
 
 19th September 2016 - Gunter Folger (cmake-V10-02-21)
 - switch to PhotonEvaporation 4.0
 
 7th September 2016 - Gunter Folger (cmake-V10-02-20)
 - switch to G4RadioactiveDecay.5.0
 
 22nd August 2016 - Ben Morgan (cmake-V10-02-19)
 - Templates/UseGeant4.cmake : Force core and per-mode flags to those used to
   build Geant4. When Geant4 is built with a single mode generator, default
   CMAKE_BUILD_TYPE for the client to that used to build this install. This
   guarantees matching of librayr/application optimization for most use cases.
   NB: No default mode can be provided if Geant4 itself was built/installed using
   multimode tool like Xcode/VS. This is because multiple modes may be installed
   at once so a sensible default cannot be set (to be looked at further).
 - Templates/Geant4Config.cmake.in : Add new Geant4_BUILD_TYPE variable to hold
   build type of install when Geant4 is installed using a single mode tool.
 - Modules/Geant4BuildProjectConfig.cmake : Set Geant4_BUILD_TYPE to CMAKE_BUILD_TYPE
   when building with a single mode tool.
 
 15th August 2016 - Gunter Folger (cmake-V10-02-18)
 - switch to G4EMLOW.6.49
 
 17th June 2016 - Gabriele Cosmo (cmake-V10-02-17)
 - Modules/Geant4OptionalComponents.cmake: set CLHEP-2.3.3.0 as the required
   version for external CLHEP library.
 
 9th June 2016 - Gunter Folger  (cmake-V10-02-16)
 - revert change in Templates/Geant4Config.cmake.in in tag cmake-V10-02-14,
     revision 97140; the coworking tags have been rejected.
 
 3rd June 2016 - Gunter Folger  (cmake-V10-02-15)
 - switch to RadioActiveDecay 4.4.1 and  G4ENSDFSTATE 1.3.1, both provided by
    Laurent.
 
 25th May 2016 - Robert Hatcher (cmake-V10-02-14)
 - Templates/Geant4Config.cmake.in : No longer use --whole-archive for
 G4physicslists on static builds; this was never possible for _WIN32 and recent
 physics list factory work makes this untenable.
 
 25th May 2016 - Ben Morgan (cmake-V10-02-13)
 - Modules/Geant4InterfaceOptions.cmake : Always add Xmu to X11_LIBRARIES when
 using Motif/OpenInventor to avoid missing symbol errors on OS X.
 
 24th May 2016 - Ben Morgan (cmake-V10-02-12)
 - Modules/Geant4OptionalComponents.cmake : Fix regex to avoid matching to "CONS"
   shape is check for all shapes.
 
 24th May 2016 - Ben Morgan (cmake-V10-02-11)
 - Modules/Geant4OptionalComponents.cmake : Initial implementation of a list
   based interface to GEANT4_USE_USOLIDS. Rather than booleans, unify USolids
   replacement into single string/list variable with following behaviour:
   1) Setting to "all", any CMake boolean true value, or a list containing either
      results in complete usolids replacement
   2) A list, i.e. "a;b;c", or shapes to replace with Usolids equivalents may be supplied.
   Validate arguments to prevent unknown shapes being set, and otherwise retain previous
   behaviour
   List allowed values in option docstring.
 - Modules/Geant4BuildProjectConfig.cmake : Ensure setting of Usolids use marker to a
   proper boolean value.
 - Templates/Geant4Config.cmake.in : Use new full boolean variable as expansion variable
   to indicate usolids support.
 
 23rd May 2016 - Ben Morgan
 - Modules/Geant4OptionalComponents.cmake : Allow developers to select
   subsets of solids to replace with USolids equivalents. Request from developers
   and CMS to assist in performance evaluation. NOT INTENDED FOR USERS!
   If GEANT4_USE_SOLIDS is set, use existing configuration/setup. If it is OFF,
   allow setting of additional CMake options, one per shape, to enable replacement
   of that shape with USolids equivalent. When any of these variables are set, set
   additional internal variable GEANT4_USE_PARTIAL_USOLIDS. Convert variables to
   internal preprocessor flags for shape/usolid activation.
 - Modules/Geant4BuildProjectConfig.cmake : Export needed USOLIDS/shape activation
   preprocessor flags for selected configuration.
 - Modules/Geant4ConfigureConfigScript.cmake : Export needed USOLIDS/shape activation
   preprocessor flags for selected configuration.
 
 28th April 2016 - Ben Morgan (cmake-V10-02-10)
 - Templates/Geant4Config.cmake.in: BUGFIX #1855. When using an external
   CLHEP, the provided FindCLHEP module is not used. Wrap call to
   find_package(CLHEP) with push/pop of CMAKE_MODULE_PATH to ensure
   Geant4's builtin module is used and not interfere with any user
   settings of CMAKE_MODULE_PATH.
 
 19th April 2016 - Gunter Folger (cmake-V10-02-09)
 -  correct Modules/genwindef/LibSymbolInfo.cpp for use with VC 64 bit compilation
 
 29th March 2016 - Gunter Folger (cmake-V10-02-08)
 -  switch to RadioActiveDecay 4.4; dataset identical to 4.3.1, packaging
     corrected to be a compressed tar file, 4.3.1 is plain tar

 - Modules/Geant4DatasetDefinitions.cmake: Use new data set G4ENSDFSTATE.1.3
 
 22nd January 2016 - Ben Morgan (cmake-V10-02-02)
 - Modules/FindCLHEP.cmake : Restore from last version. Update regexing
   of defs.h file for CLHEP 2.3.1.1 changes, retaining compatibility with
   earlier versions. Create imported targets CLHEP and CLHEP::<COMPONENT>
   to ease transition to full Config mode support once we can support it.
 - Modules/Geant4OptionalComponents.cmake : Rollback to using package-mode
   to locate CLHEP. Modify CLHEP_LIBRARIES after finding to fill this with
   the imported targets instead of absolute paths.
 - Modules/Geant4BuildProjectConfig.cmake : Add FindCLHEP.cmake to installed
   modules so that Geant4Config.cmake can refind CLHEP and hence the imported
   targets.
 - Templates/Geant4Config.cmake.in : Refind CLHEP using package-mode,
   using hardcoded CLHEP_ROOT_DIR if set as a hint.
 
 15th December 2015 - Ben Morgan (cmake-V10-02-01)
 - Templates/Geant4Config.cmake.in : Use PATHS option in find_package
   for CLHEP, setting it to discovered CLHEP_DIR. Required at present
   to provide a hint to builds of tests, which do not have
   CMAKE_PREFIX_PATH set appropriately.
 
 15th December 2015 - Ben Morgan (cmake-V10-02-00)
 - [BUGFIX #1805] : Preliminary fix for CLHEP 2.3.1.1 config error
 - Modules/FindCLHEP.cmake : REMOVED as obsolete
 - Modules/Geant4OptionalComponents.cmake : Use NO_MODULE in
   find_package(CLHEP) so that CLHEPConfig.cmake is preferred.
   Retain use of CLHEP_ROOT_DIR temporarily for transition in
   testing system
 - Modules/Geant4BuildProjectConfig.cmake : Remove setting of explicit CLHEP
   directory, defering this to find_package call in Geant4Config.cmake
 - Templates/Geant4Config.cmake.in : Use namespaced name for Geant4 cmake
   directory to avoid upstream clashes.
   Add explicit call to find_package(CLHEP) so that imported targets are refound.
   Move inclusion of targets file to after setup steps to ensure all external
   targets exist before this is included. This is also to help further work
   on use of imported targets.
 - Modules/Geant4ConfigureConfigScript.cmake : Extract LOCATION property from
   CLHEP targets to provide setting of lib paths in geant4-config
 - Templates/geant4-config.cmake.in : Remove explicit calls to clhep-config
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Extract LOCATION
   properties from CLHEP imported targets.
 
 
 25th November 2015 - Ben Morgan (cmake-V10-01-41)
 - Modules/Geant4InterfaceOptions.cmake : Move force Qt4 option
   alongside use Qt option so that it can be set in Curses/GUI before
   first-pass search for Qt.
 - Modules/Geant4BuildModes.cmake : Change default build mode for
   single config generators to RelWithDebInfo to match testing
   system and UNIX conventions.
 - Modules/Geant4LibraryBuildOptions.cmake : Add new MSVC only option
   GEANT4_BUILD_MSVC_MP, defaulting to OFF. When ON, it prepends /MP
   to CMAKE_CXX_FLAGS to enable file level parallel compilation when
   using MSBuild.
 
 23rd November 2015 - Ben Morgan (cmake-V10-01-40)
 - Modules/FindROOT.cmake : Apply patch from Ivana Hrivnacova to provide
   compatibility with ROOT6 and allow usage of ROOTConfig.cmake, if
   available.
 - Modules/Geant4MakeRules_cxx.cmake : Correct checking of Intel compiler
   to use better CMAKE_CXX_COMPILER_ID variable.
 - Modules/Geant4InterfaceOptions.cmake : Allow user to force search for
   Qt4 only when GEANT4_USE_QT is selected. Requested on User Forum by
   Jan Pipek (http://hypernews.slac.stanford.edu/HyperNews/geant4/get/installconfig/1766.html)
 
 18th November 2015 - Ben Morgan (cmake-V10-01-39)
 - Modules/IntelCompileFeatures.cmake : Fix logic error in conditionals
   that resulted in only one branch being followed and a non-complete
   set of compile features being set.
 
 17th November 2015 - Ben Morgan (cmake-V10-01-38)
 - Modules/Geant4LibraryBuildOptions.cmake : To provide backward
   compatibility, allow GEANT4_BUILD_CXXSTD to be supplied as either
   an epoch like '11' or as 'c++<epoch>'. If the latter form is supplied
   postprocess to remove the 'c++' so that standards can be dealt with in
   a uniform numeric manner.
 
 17th November 2015 - Ben Morgan (cmake-V10-01-37)
 - Use CMake Compile Features to setup C++ Standard
 - Modules/Geant4MakeRules_cxx.cmake : Remove setup of standard selection
   via compiler version checking.
 - Modules/Geant4LibraryBuildOptions.cmake : Create list of compile
   features required by Geant4, per C++ Taskforce report. For 10.2, do
   not include
   - cxx_deleted_functions
   - cxx_generalized_initializers
   - cxx_constexpr
   - cxx_inheriting_constructors
   to provide backward compatibility with Visual Studio 2013 (MSVC 18).
   Maintain GEANT4_BUILD_CXXSTD option to allow user to choose between
   C++11 and C++14 standards. When newer standard is chosen, require that
   compiler supports at least one feature from that standard, and add all
   supported features of that standard to the required list.
 - Modules/IntelCompileFeatures.cmake : CMake does not currently provide
   builtin compile features for ICC. Use info provide by Intel to support
   compile features for this compiler.
 - Modules/Geant4MacroLibraryTargets.cmake : Use target_compile_features
   to set the required features on all Geant4 targets.
 - Modules/Geant4BuildProjectConfig.cmake,
   Templates/Geant4Config.cmake.in, Templates/geant4-config.in: Update
   setting of flags and standard used to obtain information from
   compile features.
 
 10th November 2015 - Gabriele Cosmo (cmake-V10-01-36)
 - Put CLHEP version 2.3.1.0 as the minimum required in script
   Modules/Geant4OptionalComponents.cmake.

 22nd October 2015 - Ben Morgan (cmake-V10-01-31)
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Add export
   of TOOLS_FONT_PATH to environment when Freetype support is enabled,
   pointing to the fonts/ subdirectory of Geant4's share directory.
   For the buildtree, point it to PROJECT_SOURCE_DIR/source/analysis/fonts
   Treat TOOLS_FONT_PATH as a UNIX style PATH variable with normal
   separators.
 - Templates/geant4-env-skeleton.in, Templates/geant4make-skeleton.in :
   Add export variables for configuring TOOLS_FONT_PATH variable.
 
 21st October 2015 - Ben Morgan (cmake-V10-01-30)
 - Modules/Geant4ConfigureConfigScript.cmake : Export value of
   GEANT4_USE_FREETYPE to geant4-config to allow this to report support
   status of freetype in G4analysis
 - Templates/geant4-config.in : Add freetype feature to report status of
   freetype support in G4analysis
 - Templates/Geant4Config.cmake.in : Add freetype component to require
   freetype support in G4analysis.
 
 19th October 2015 - Ben Morgan
 - Modules/Geant4OptionalComponents.cmake : Add new GEANT4_USE_FREETYPE
   option, OFF by defaults, to allow user to enable Freetype support
   in analysis library.
 
 12th October 2015 - Gunter Folger (cmake-V10-01-29)
 - Modules/Geant4DatasetDefinitions.cmake: Use new data set G4EMLOW.6.47
 
 8th October 2015 - Ben Morgan (cmake-V10-01-28)
 - Modules/Geant4OptionalComponents.cmake: Only allow use of system
   USolids. Remove old "USE_SYSTEM_USOLIDS" option, and always call
   find_package for USolids.
 - Modules/GeantBuildProjectConfig.cmake, Templates/Geant4Config.cmake.in:
   Remove old system usolids settings as USolids is always system now
 - Modules/Geant4ConfigureConfigScript.cmake, Templates/geant4-config.in:
   Remove old system Usolids settings as Usolids is alsways system now.
   Ensure include paths exported.
 
 6th October 2015 - Ben Morgan (cmake-V10-01-27)
 - Modules/Geant4MakeRules_cxx.cmake: Update AppleClang detection to
   for Xcode 7 and match to CMake 3's AppleClang rules. Provide
   CXXSTD_IS_AVAILABLE for MSVC 19 so that appropriate standard selection
   preprocessor symbols are defined.
 
 1st October 2015 - Gunter Folger (cmake-V10-01-26)
 - Modules/Geant4DatasetDefinitions.cmake: Use new data set G4EMLOW.6.46
 
 18th September 2015 - Ben Morgan (cmake-V10-01-25)
 - Modules/Geant4LibraryBuildOptions.cmake, Modules/Geant4MacroLibraryTargets, Modules/GeantBuildProjectConfig.cmake: Allow both static and shared libs
   to be built on Windows. Remove G4LIB_BUILD_DLL preprocessor def from
   global settings, only adding it to the public compile defs of the
   resulting DLL. To create DLL, always compile dedicated archive library
   separate from installed version. Compile the sources of this dedicated
   archive library with G4LIB_BUILD_DLL set so that DLL relevant symbols
   are used.
 
 16th September 2015 - Gunter Folger (cmake-V10-01-24)
 - Modules/Geant4DatasetDefinitions.cmake: Use new data set G4ENSDFSTATE.1.1
 
 14th September 2015 - Ben Morgan (cmake-V10-01-23)
 - Modules/Geant4CTest.cmake, Modules/Geant4InstallData.cmake, Modules/Geant4ToolchainBackwardCompatibility.cmake: Export and use G4ENSDFDATA dataset
   and environment variable. It will become the default to use this dataset
   so requires export.
 
 1st September 2015 - Gunter Folger (cmake-V10-01-22)
 - Modules/Geant4DatasetDefinitions.cmake: Use new data set G4EMLOW.6.45
 
 31st August 2015 - Gabriele Cosmo (cmake-V10-01-21)
 - Modules/Geant4OptionalComponents.cmake, GeantBuilsProjectConfig.cmake and
   Templates/geant4-config.in: added specific compilation flag
   "-DG4GEOM_USE_SYS_USOLIDS" to distinguish build with sys-installed
   USolids/VecGeom module (temporary, until internal USolids module will be
   removed).
 
 12th August 2015 - Gabriele Cosmo (cmake-V10-01-20)
 - Modules/Geant4MakeRules_cxx.cmake: removed -gcc-sys in CMAKE_CXX_FLAGS
   for the Intel compiler, as no longer necessary.
 - Modules/Geant4LibraryBuildOptions.cmake: removed try-compile block for
   atomics on Intel compiler, as no longer necessary.
 
 7th August 2015 - Gabriele Cosmo (cmake-V10-01-19)
 - Modules/Geant4MakeRules_cxx.cmake: replaced -no-gcc with -gcc-sys
   in CMAKE_CXX_FLAGS when using Intel compiler, to allow for GNU macros
   to be defined when compiling system headers.
 
 31st July 2015 - Ben Morgan (cmake-V10-01-18)
 - Modules/Geant4MacroLibraryTargets.cmake : Updates for migration to
   CMake >= 2.8.12. Use generator expressions in setting of per-mode
   compile definitions for Geant4 libs. Use INTERFACE_LINK_LIBRARIES
   instead of LINK_INTERFACE_LIBRARIES on Windows. Replace use of
   INSTALL_NAME_DIR with MACOSX_RPATH property for OS X libraries.
 
 29th July 2015 - Ben Morgan
 - Module/Geant4LibraryBuildOptions.cmake : Add try-compile for
   atomics with Intel in C++1X mode and use Intel atomic if system
   cannot support them. Reported by Andrea Dotti,
   because Geant4 uses Intel's no-gcc flag to prevent thread local
   issues, system atomic header will be used by default. If system
   compiler does not support atomic, builds will fail.
 
 27th July 2015 - Ben Morgan (cmake-V10-01-17)
 - Modules/Geant4MakeRules_cxx.cmake : Always use libc++ with Apple
   Clang so that std-supporting library is used for C++11 mode on
   older Mac systems where libstdc++ is the default.
 
 23rd July 2015 - Ben Morgan (cmake-V10-01-16)
 - Modules/Geant4MacroLibraryTargets.cmake : Update rules for .def
   file generation to use new output dirs and to separate .def files
   for each build mode.
 - Modules/Geant4MakeRules_cxx.cmake : To permit transition to C++11
   update std-flag setting rules to only allow C++11 builds with compiler
   versions that are know to support the features in current use.
 
 22nd July 2015 - Ben Morgan (cmake-V10-01-15)
 - Modules/Geant4MakeRules_cxx.cmake : When compiler allows selection
   of C++ standard and allows C++0x/11, default to using this standard.
 
 13th July 2015 - Ben Morgan (cmake-V10-01-14)
 - Modules/Geant4LibraryBuildOptions.cmake : Migrate output directories
   for build products to use same layout as install tree. For single
   mode generators (Makefiles/Ninja), products are output to a
   'BuildProducts' subdir of the main binary dir which holds bin/lib
   directories as derived from requested install dirs. With multimode
   generators (Xcode/VS), 'BuildProducts' holds an extra directory layer,
   one per build mode, under which the same bin/lib structure is used.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Update to use
   correct output dirs.
 - Modules/Geant4ConfigureConfigScript.cmake : Note that this will not
   work for multimode builds.
 
 8th June 2015 - Ben Morgan (cmake-V10-01-13)
 - Templates/Geant4Config.cmake.in : Always re-find Qt5 via find_package
   if Geant4 was configured with Qt5 support. Qt5 libraries are in
   public link interface of G4interfaces and G4OpenGL whether or not it
   is activated for an application, so must always be linked. Without
   refinding, dangling imported targets are left in the link interfaces
   of G4interfaces and G4OpenGL.
 
 26th May 2015 - Gunter Folger (cmake-V10-01-12)
 -  Modules/Geant4DatasetDefinitions.cmake: Use new data set G4EMLOW.6.44
 
 19th May 2015 - Gunter Folger (cmake-V10-01-11)
 -  Modules/Geant4DatasetDefinitions.cmake: Use new data set G4EMLOW.6.43
 
 5th May 2015 - Ben Morgan (cmake-V10-01-10)
 - Modules/Geant4ConfigureModulefile.cmake : Genarate a modulefile
   for the build tree. Requested by developers, but otherwise unsupported.
 - Templates/geant4-modulefile.in : Update export variables to allow
   transparent configuration of build/install tree versions.
 
 29th April 2015 - Ben Morgan (cmake-V10-01-09)
 - Modules/Geant4MakeRules_cxx.cmake: Add `-no-gcc` to CMAKE_CXX_FLAGS
   when using Intel compiler. This is temporary fix to give
   matching flags against old GNUmake build. It requires further checks
   to understand full behaviour of this flag to tune code versus
   Intel's `-gcc-sys` flag and `__INTEL_COMPILER` macro.
 
 22nd April 2015 - Ben Morgan (cmake-V10-01-08)
 - Modules/FindCLHEP.cmake: Add CLHEP_ROOT_DIR to CMake cache, allowing
   it to be editted in the CMake curses/GUI. Use unset command to remove
   LIBRARY and INCLUDE_DIR variables for CLHEP from the cache when
   CLHEP_ROOT_DIR is changed.
 - Templates/geant4-env-skeleton.in: Add expansion entry for CLHEP library
   path
 - Modules/Geant4ToolchainBackwardCompatibility.cmake: Export setting
   of dynamic library path to prepend system CLHEP's library path in
   geant4.(c)sh
 
 17th April 2015 - Ben Morgan (cmake-V10-01-07)
 - Fixes for JIRA DEV-185 (Allow use of system CLHEP granular libraries)
 - Modules/FindCLHEP.cmake: Allow component arguments to be supplied to
   find_package, each component being a CLHEP granular library. Support
   dependencies between components, and fail on REQUIRED if any requested
   component or dependency is not found. Set cache variables for each requested
   component library, and fill CLHEP_LIBRARIES with the requested libraries
 - Modules/Geant4OptionalComponents.cmake: Provide new advanced option
   GEANT4_USE_SYSTEM_CLHEP_GRANULAR, which can be set to enable use of CLHEP
   granular libraries from the system. When activated, use new FindCLHEP
   interface to search for Geant4's required components.
 - Templates/Geant4Config.cmake.in: Export and document a new variable,
   Geant4_system_clhep_ISGRANULAR that clients can query to check whether
   the system CLHEP was linked in granular mode.
 - Modules/Geant4ConfigureConfigScript.cmake: Process and export system CLHEP
   library list to support either singular or granular CLHEP libraries.
 - Templates/geant4-config.in: Support CLHEP granular library listing in
   '--libs' argument.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake: Export CLHEP_LIB env var
   to support use of system CLHEP libraries in granular mode.
 - Templates/geant4make-skeleton.in: Export CLHEP_LIB env var to support
   system CLHEP libs in granular mode.
 
 15th April 2015 - Ben Morgan (cmake-V10-01-06)
 - Modules/Geant4MakeRules_cxx.cmake: Update AppleClang version regex for
   Xcode 6.1. This version adds the patch number to the "based on LLVM"
   id. The full version number is now derived.
 
 20th March 2015 - Gabriele Cosmo (cmake-V10-01-05)
 - Modules/Geant4MacroLibraryTargets.cmake: Added external G4geomUSolids
   library to static linkage list. Addressing problem report #1725.
 
 2nd February 2015 - Ben Morgan
 - Modules/Geant4CPackBase.cmake: Exclude directories named "test"
   and "tests" from source package. Provide function to pad version
   triplet entries to two digits (with zeros), and name source package
   following convention of standatd release proceedure. CAVEATS: Patch
   version still included with initial release, no use of beta/patch/rc
   tags in patch numbering.
 
 29th January 2015 - Ben Morgan (cmake-V10-01-04)
 - Modules/Geant4MakeRules_cxx.cmake: Minor update to only use c++11
   on Intel 15 compiler and better. Though this standard can be used
   on slightly earlier versions, only 15 has full features (for Geant4's
   needs). We would like to be consistent in standard use so that 'c++0x'
   is always used for compilers with partial support (even if 'c++11' is
   allowed), reserving 'c++11' for fully supported cases. This still
   needs review for GNU and Clang.
 
 29th January 2015 - Ben Morgan (cmake-V10-01-03)
 - Modules/Geant4MakeRules_cxx.cmake: Add support for compiling against
   c++1y standard for GNU and Clang compilers. Add support for compiling
   against c++11 standard for Intel compiler.
 
 17th December - Ben Morgan (cmake-V10-01-02)
 - Modules/Geant4InterfaceOptions.cmake: BUGFIX #1683. Correct search
   path for X11 libraries to ensure location of Xquartz libs on OS X.
 
 15th December 2014 - Gunter Folger (cmake-V10-01-01)
 -  Modules/Geant4DatasetDefinitions.cmake: Use new data set G4EMLOW.6.42
 
 05th December 2014 - Ben Morgan (cmake-V10-01-00)
 - Modules/Geant4LibraryBuildOptions.cmake: When on OS X, check
   whether compiler IDed as Clang is actually g++ via command
   path. Ensures that "GEANT4_COMPILER" is correctly set for
   GNUmake compatibility.
 
 01st December 2014 - Ben Morgan (cmake-V10-00-37)
 - Modules/Geant4BuildProjectConfig.cmake: Correct export of USolids
   system headers so that these are exported whether or not USolids
   are used to replace G4 solids.
 
 18th November 2014 - Ben Morgan (cmake-V10-00-36)
 - Templates/UseGeant4.cmake : Include Geant4 headers as SYSTEM and after
   other headers. This is to help to suppress warnings when user has
   more stringent compiler settings than us.
 
 12th November 2014 - Ben Morgan (cmake-V10-00-35)
 - Modules/Geant4LibraryBuildOptions.cmake: Remove GEANT4_BUILD_TPMALLOC
   as this is no longer required
 
 11th November 2014 - Gunter Folger (cmake-V10-00-34)
 - Modules/Geant4DatasetDefinitions.cmake: update md5sum
    for G4EMLOW6.21 after correction of files access permissions.

 - Modules/Geant4DatasetDefinitions.cmake: RadioactiveDecay4.2
    and update md5sum for G4EMLOW6.21 after correction of files
   access permissions.
 
 07th November 2014 - Ben Morgan (cmake-V10-00-32)
 - Modules/Geant4OptionalComponents.cmake : BUGFIX: Failures of static
   builds traced to typo in USolids settings in static mode where
   EXPAT_LIBRARIES was overwritten. Correct typo.
 
 30th October 2014 - Ben Morgan (cmake-V10-00-31)(INTERNAL)
 - Modules/Geant4OptionalComponents.cmake : Update USolids configuration
   to decouple GEANT4_USE_USOLIDS and GEANT4_USE_SYSTEM_USOLIDS
   options.
   - GEANT4_USE_USOLIDS ON means that Geant4 solids are replaced with
     USolids equivalents, OFF means Geant4 solids and USolids are available
   - A USolids lib must ALWAYS be availble, so GEANT4_USE_SYSTEM_USOLIDS
     simply switches between these.
 - Templates/Geant4Config.cmake.in : decouple GEANT4_USE_USOLIDS and
   GEANT4_USE_SYSTEM_USOLIDS
 - Templates/geant4-config.in : decouple GEANT4_USE_USOLIDS and
   GEANT4_USE_SYSTEM_USOLIDS
 
 30th October 2014 - Ben Morgan (cmake-V10-00-30)(INTERNAL)
 - Support builtin/system USolids library
 - Modules/Geant4OptionalComponents.cmake : Update USolids configuration
   use internal G4geomUSolids by default if USolids support requested.
   Add dependent option to allow system USolids to be searched for.
   This assumes that USolids will supply a "USolidsConfig.cmake" file
 - Modules/Geant4BuildProjectConfig.cmake : Update to export USolids
   settings as required.
 - Templates/Geant4Config.cmake.in : Update to provide new USolids
   component and relevant variables and settings
 - Modules/Geant4ConfigureConfigScript.cmake : Update to export
   USolids settings as required
 - Templates/geant4-config.in : Update to support USolids builtin/system
   switch.
 
 23rd October 2014 - Ben Morgan (cmake-V10-00-29)
 - Templates/geant4-config.in : Add command line arguments to report
   C++ standard compiled against and TLS model used if multithreading
   support available.
   Add presence of static libs as a feature argument that can be checked.
 - Modules/Geant4ConfigureConfigScript.cmake : Export yes/no value
   indicating presence of static libraries to config script.
 - Templates/Geant4Config.cmake.in : Add variables to indicate C++
   standard compiled against and TLS model used. Latter is only set
   if multithreading support is available.
 - Modules/
 
 22nd October 2014 - Gunter Folger (cmake-V10-00-28)
 - Modules/Geant4DatasetDefinitions.cmake: G4EMLOW.6.41
 
 21st October 2014 - Ben Morgan (cmake-V10-00-27)
 - Modules/Geant4ConfigureModulefile.cmake : New file to configure
   and install a basic Environment Modules modulefile for Geant4.
   Provides basic Path/Datapath settings only, in line with geant4.(c)sh
   scripts. Because the location of modulefiles can be highly system
   dependent, install file in datarootdir with absolute paths coded in.
   Allows file to be moved later on as required on the system and
   patched accordingly.
 - Templates/geant4-modulefile.in : basic template for a modulefile
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : include and
   call functionality in Geant4ConfigureModulefile.
 
 20th October 2014 - Ben Morgan
 - Modules/Geant4ToolchainBackwardCompatibility.cmake,
   Templates/geant4make-skeleton.in: Revert changes introduced to
   support modulefiles due to uneeded variables being exported.
 
 10th October 2014 - Andrea Dotti (cmake-V10-00-26)
 - Modules/FindROOT.cmake add ROOT_BIN_DIR variable to point to the
   path of root executables. Needed to use hadd application for
   physics testings (merging of output files for MT)
 
 08th October 2014 - Ben Morgan (cmake-V10-00-25)
 - Templates/UseGeant4.cmake : BUGFIX #1663, Append existing CMake
   CXX/EXE_LINKER flags to Geant4 flags when setting overall CMake flags.
   This allows users to override the base set if needed, at their own
   risk.
 
 26th September 2014 - Ben Morgan (cmake-V10-00-24)
 - Modules/Geant4ToolchainBackwardCompatibility.cmake,
   Templates/geant4make-skeleton.in: Revert changes introduced to
   support modulefiles due to incorrect installation names of scripts.

   from internal library link list when building global libraries.
 
 26th August 2014 - Gunter Folger (cmake-V10-00-21)
 - Modules/Geant4DatasetDefinitions.cmake: G4EMLOW.6.40
 
 19th August 2014 - Gunter Folger (cmake-V10-00-20)
 - Modules/Geant4DatasetDefinitions.cmake: G4NDL.4.5
 
 08th July 2014 - Andrea Dotti (cmake-V10-00-19)
 - Templates/UseGeant4_internal.cmake in geant4_add_test function convert
   character '=' present in command line to be executed to '@'
 - Modules/Geant4TestDriver.cmake convert back character '@' to '=' for
   command line to be executed in test
 Both changes are needed to support "offloading" of tests (e.g. will be
 used by testing on Xeon Phi co-processors that require complex command
 lines containing '=' character).
 
 06th June 2014 - Ben Morgan (cmake-V10-00-18)
 - Templates/geant4-config.in : Add zlib and g3tog4 to list of features
   that --has-feature recognizes and can query (Patch from Ivana
   Hrivnacova)
 
 05th June 2014 - Gunter Folger (cmake-V10-00-17)
 - Modules/Geant4DatasetDefinitions.cmake: G4EMLOW6.39

 - Modules/Geant4DatasetDefinitions.cmake: G4EMLOW6.38
 
 10th April - Ben Morgan (cmake-V10-00-13)
 - Modules/Geant4LibraryBuildOptions.cmake: When building against the C++11
   standard, append -DG4USE_STD11 to CMAKE_CXX_FLAGS. Requested by Gabriele
   Cosmo (DEV-138). Known issues: Provides no guarantee that required
   C++11 features are present. Does not work on MSVC yet, but neither
   will the parts of the code making use of C++11 features.
 
 18th March 2014 - Gunter Folger (cmake-V10-00-12)
 - Modules/Geant4DatasetDefinitions.cmake: G4EMLOW6.37

 - Modules/Geant4Config.cmake.in : When static libraries are used,
   wrap G4physicslists library with flags suitable to import whole
   archive. Implemented for GNU/Clang/Intel compilers. Other compilers
   require further checks on flags and how to apply to single library.
   This functionality is needed to support global registration of
   factories.
 
 5th March 2014 - Ben Morgan (cmake-V10-00-08)
 - Modules/Geant4MacroLibraryTargets.cmake : Fixup usage of shared/static
   builtin libraries. Ensure that shared builtins do not get linked to
   static.
 - Templates/Geant4Config.cmake.in : Add new component 'static' allowing
   user to select static Geant4 libraries if they are available.
 
 26th February 2014 - Gunter Folger (cmake-V10-00-07)
 - Modules/Geant4DatasetDefinitions.cmake: PhotonEvaporation3.1
 
 26th February 2014 - Gunter Folger (cmake-V10-00-06)
 - Modules/Geant4DatasetDefinitions.cmake: RadioactiveDecay4.1
 
 18th February 2014 - Ben Morgan (cmake-V10-00-05)
 - Modules/Geant4ConfigureConfigScript.cmake : Export use of builtin
   zlib or otherwise to geant4-config (Bugfix #1572).
 - Template/geant4-config.in : Add builtin zlib to list of features,
   adding G4zlib to list of libraries when used (Bugfix #1572).
 - Template/geant4-config.in : Replace use of GNU awk extension 'length'
   for determining number of datasets. Use return value of split function
   to get length of array. Problem reported on Hypernews:
   http://hypernews.slac.stanford.edu/HyperNews/geant4/get/installconfig/1614.html
 
 17th February 2014 - Ben Morgan (cmake-V10-00-04)

   G4LIB_{BUILD,USE}_EXPAT as for ZLIB. Fixes Bug #1567
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Export
   G4LIB_{BUILD,USE}_EXPAT based on value of GEANT4_USE_SYSTEM_EXPAT.
   Fixes Bug #1567.
 
 21st January 2014 - Jonathan Madsen (cmake-V10-00-03)
 - Updated Modules/Geant4InterfaceOptions.cmake to include /opt/X11
    paths that are now the standard places for X11 and OpenGL on Mac OSX
    as of Mavericks (OS X 10.9). Without these paths configuring CMake with
    GEANT4_USE_OPENGL_X11=ON fails
 
 18th December 2013 - Gunter Folger (cmake-V10-00-02)
 - Modules/Geant4TestDriver.cmake: CTEST_TEST_TIMEOUT is empty, or
    its setting is not visible.
   Directly using environment variable CTEST_TIMEOUT finally works.
 
 16th December 2013 - Gunter Folger (cmake-V10-00-01)
 - Modules/Geant4TestDriver.cmake: fix typo introduced in previous tag
 
 16th December 2013 - Gunter Folger (cmake-V10-00-00)

   default timeout
 
 28th November 2013 - Ben Morgan (cmake-V09-06-45)
 - Modules/Geant4CTest.cmake : Remove G4ENSDFSTATE dataset from list
   exported to the testing environment, as it should not be used by
   default.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Remove G4ENSDFSTATE
   from datasets exported to the environment. This is because this dataset
   should not be set in the environment by default.
 - Modules/Geant4InstallData.cmake : Remove G4ENSDFSTATE dataset from
   export definitions. The ENSDF data is not intended to be used by
   default, and any setting of its environment variable changes the
   behaviour of Geant4 (i.e. it's an active rather than passive variable).
 
 27th November 2013 - Gunter Folger (cmake-V09-06-44)
 - Modules/Geant4DatasetDefinitions.cmake: Add ENSDFSTATE data
 
 27th November 2013 - Ben Morgan (cmake-V09-06-43)

   for Intel compiler to "-ftls-model=initial-exec -pthread" as for GNU and
   Clang.
 
 26th November 2013 - Ben Morgan (cmake-V09-06-42)
 - Modules/Geant4LibraryBuildOptions.cmake : Mark GEANT4_BUILD_MULTITHREADED
   as advanced on Win32, and emit a warning on Win32 if it is activated.
   This allows developers to keep working whilst warning users about the
   non-support.
 
 21st November 2013 - Ben Morgan (cmake-V09-06-41)
 - Modules/Geant4InterfaceOptions.cmake : Fix bug in checking of status
   of Xmu include path and library variables that resulted in no error
   being emitted if these were not found.
 
 19th November 2013 - Ben Morgan (cmake-V09-06-40)
 - Modules/Geant4ConfigureConfigScript.cmake : Fix bug in list manipulation

 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Add support
   for export of multithreading and application PATH variables.
 - Templates/geant4make-skeleton.in : Export G4MULTITHREADED variable,
   and prepend binary directory to PATH to provide direct access to
   geant4-config.
 - Modules/Geant4ConfigureConfigScript.cmake : Add support for export
   of multithreading variables.
 - Templates/geant4-config.in :
    Bug fixes : add core compiler flags to cflags

                cflags for multithreading if Geant4 built in MT)
    New feature : Implement post install of datasets. Supplying the
                  --install-data flag will perform a download and
                  install of all datasets to the configured data directory
                  of Geant4.
 - Modules/Geant4InstallData.cmake : Append filename and md5 to tuples
   exported by geant4_export_datasets. This is used by geant4-config to
   set up the post-install of datasets.

 - Templates/Geant4UseQt5.cmake.in : New file providing forward
   compatibility of compilation against Qt5 with no changes required
   to CMake scripts in interfaces and OpenGL.
 - Modules/Geant4InterfaceOptions.cmake : Search for Qt5 first, then Qt4.
   When Qt5 is found, configure forward compatibility use file using
   Geant4UseQt5.cmake.in template. If Qt5 is not found, unset its usage
   and require loacation of Qt4.
 
 21st October 2013 - Gunter Folger (cmake-V09-06-28)
 - switch to G4NEUTRONXS 1.4

 26th September 2013 - Ben Morgan (cmake-V09-06-26)
 - Modules/Geant4LibraryBuildOptions.cmake : When building in
   multithreaded mode on a UNIX system, perform a compile test to check
   that compiler supports thread local storage via availability of
   "__thread". Emit a FATAL_ERROR if the compiler does not support TLS,
   reporting this and the compiler used.
 - Templates/geant4-config.cmake.in : Implement new --check-datasets and
   --install-datasets tasks. The former checks that the known datasets are
   installed in the configured location, reporting status. The latter is a
   stub for implementing post-install download and unpack of datasets
 
 17th September 2013 - Ben Morgan (cmake-V09-06-25)
 - Templates/geant4-config.cmake.in : Expand export variable holding
   list of dataset tuples. Process list from CMake ';' separated to
   shell ' ' separated list. Implement new '--datasets' argument to
   print out space separated dataset name, envvar name and path, with
   information for each dataset on a separate line.
 - Templates/Geant4Config.cmake.in : Expand export variable holding
   list of dataset tuples. Process list to create variable holding a
   list of dataset names, plus variables, one per dataset, holding the
   dataset environment variable and configured path.
 - Modules/Geant4ConfigureConfigScript.cmake : Call geant4_export_datasets
   function before configuration of build/install tree version(s) of
   geant4-config so dataset information can be exported to it
 - Modules/Geant4BuildProjectConfig.cmake : Call geant4_export_datasets
   function before configuration of build/install tree version(s) of
   Geant4Config.cmake so dataset information can be exported to the
   CMake config script.
 - Modules/Geant4InstallData.cmake : Implement new geant4_export_datasets
   function. Write list of dataset tuples to an output variable, each
   tuple consisting of dataset name, envvar name and path separated by "|"
   Use option argument BUILD|INSTALL to use build and install paths for
   datasets respectively.
 
 16th September 2013 - Ben Morgan (cmake-V09-06-24)

     needed by test202.
 
 22nd August 2013 - Ben Morgan (cmake-V09-06-22)
 - Modules/Geant4MakeRules_cxx.cmake : Check for "Apple LLVM" string
   in output of regex parse of "clang++ -v" command output. If string is
   found, re-parse string to extract LLVM version on which Apple LLVM is
   based because this reflects the true LLVM, and hence C++ Standard
   support, of the compiler. Fixes problem with being unable to change
   C++ Standard with latest Xcode reported by Gabriele Cosmo.
 
 16th August 2013 - Ivana Hrivnacova (cmake-V09-06-21)
 - Suppress error messages from FindAIDA module for informative options.
   This fixes problem report #1485.
 
 23rd July 2013 - Gunter Folger (cmake-V09-06-20)
 - Update datasets for NDL to NDL4.4
 
 23rd July 2013 - Ben Morgan (cmake-V09-06-19)

   --has-feature for clhep feature.
 
 11th June 2013 - Gunter Folger (cmake-V09-06-16)
 - Update md5sum for NDL after removal of data for Z>92
 
 11th June 2013 - Gunter Folger (cmake-V09-06-15)
 - Update datasets for NDL, EMLOW, and RadioactiveDecay
 
 11th June 2013 - Pere Mato (cmake-V09-06-14)
 - Modules/FindROOT.cmake : Minor changes for gccxml dictionary generation.
 
 28th May 2013 - Ben Morgan (cmake-V09-06-13)
 - Modules/Geant4LibraryBuildOptions.cmake : Add option
   GEANT4_BUILD_TPMALLOC. It defaults to OFF, and is set to OFF if
   GEANT4_BUILD_MULTITHREADED is OFF or the platform is WIN32.
   When set, this adds a global compiler definition G4TPMALLOC.
   Feature requested by Andrea Dotti.
 
 22nd May 2013 - Ben Morgan (cmake-V09-06-12)
 - Modules/FindROOT.cmake : Remove "/usr/include" from list of
   include directories passed to rootcint in root_generate_dictionary
   function. Needed to workaround bug in rootcint reported by Andrea
   Dotti.
 
 7th May 2013 - Ben Morgan (cmake-V09-06-11)
 - Modules/Geant4OptionalComponents.cmake : Set variables
   GEANT4_USE_BUILTIN_{CLHEP,EXPAT,ZLIB} when the builtin versions
   of these packages are used. This is to assist the generation of
   Geant4Config.cmake using simple expansion variables
 - Templates/Geant4Config.cmake.in : Add and document new variables
   Geant4_builtin_{clhep,expat,zlib}_FOUND which are expanded to
   the value of GEANT4_USE_BUILTIN_{CLHEP,EXPAT,ZLIB} respectively.
 - These fixes are applied to support an issue in the nanobeam example,
   which requires the full CLHEP, so must check that the builtin
   version is not used. Whilst the test build is protected in
   tests/ctests/CMakeLists.txt, the nanobeam example uses an
   internal Geant4 variable to check for an external CLHEP, and so
   always fails.
 
 6th May 2013 - Gunter Folger (cmake-V09-06-10)
 - modification for internal zlib:
    ZLIB_INCLUDE_DIRS: added ${PROJECT_BINARY_DIR}/source/externals/zlib to
     make generated zconf.h available; as side effect this zconf.h will be
     installed.
 
 22nd April 2013 - Gabriele Cosmo (cmake-V09-06-09)
 - Fixed comments in scripts Geant4MakeRules_cxx.cmake and
   Geant4LibraryBuildOptions.cmake...
 
 15th April 2013 - Ben Morgan (cmake-V09-06-08)
 - Modules/Geant4MakeRules_cxx.cmake : Use -pthread flag for clang and
   gcc compilers in preference to -lpthread. Remove -lpthread from
   exe linker flags as the compiler flag should get passed to this.
 - Modules/Geant4LibraryBuildOptions.cmake : Remove addition of MT flags
   from exe linker flags, as main CXX flags should handle this.
 
 9th April 2013 - Andrea Dotti
 - Adding -lpthread to GCC linker flags if GEANT4_BUILD_MULTITHREADED is on.
 
 25th March 2013 - Ben Morgan
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : BUGFIX #1399
   Applied Mike's patch for selflocation to C-shell template
   generation.
 
 25th March 2013 - Ben Morgan (cmake-V09-06-07)
 - Modules/Geant4OptionalComponents.cmake : BUGFIX #1322 Noted that
   FindZLIB in CMake < 2.8 does not set the ZLIB_INCLUDE_DIRS variable,
   so set it manually to ensure uniform behaviour in ZLIB clients.
 
 25th March 2013 - Ben Morgan
 - Modules/Geant4OptionalComponents.cmake : BUGFIX #1322 Enable option
   GEANT4_USE_SYSTEM_ZLIB to locate system zlib if requested and otherwise
   use internal version. This will co-work with externals-V09-06-00.
   It *breaks* the analysis module, and HepRep module requires adjustment
   as reported in above bug report to ensure zlib is enabled.
 
 25th March 2013 - Ben Morgan (cmake-V09-06-06)
 - Modules/Geant4MacroLibraryTargets.cmake : BUGFIX #1353 : Add a build
   mode dependent compiler definition to the build of each Geant4 target
   in the form GEANT4_DEVELOPER_<CONFIG> where <CONFIG> is the uppercased
   build mode as determined from CMAKE_CONFIGURATION_TYPES or
   CMAKE_BUILD_TYPE as appropriate for the generator.
   Checked on Linux and Mac with Make/Xcode generators, tagging for testing
 
 1st March 2013 - Ben Morgan (cmake-V09-06-05)
 - Templates/Geant4Config.cmake.in : Add 'multithreaded' component to
   indicate if Geant4 was built with multithreading. If it is requested,
   and the build is multithreaded, append the -DG4MULTITHREADED compile
   definition to GEANT4_DEFINITIONS. Note clear this is the best option
   yet, but awaits testing and example builds.
 - Modules/Geant4LibraryBuildOptions.cmake : Add option
   GEANT4_BUILD_MULTITHREADED which when ON, adds the compiler definition
   -DG4MULTITHREADED globally, and appends GEANT4_MULTITHREADED_CXX_FLAGS
   to CMAKE_CXX_FLAGS. Set to OFF by default as requested for testing.
 - Modules/Geant4MakeRules_cxx.cmake : For GNU compiler only (which may also
   apply to clang compiler with CMake 2.8.2 and earlier), set a new variable
   GEANT4_MULTITHREADED_CXX_FLAGS to hold any extra flags needed by
   multithreaded build, but would conflict with sequential. Not clear
   this separation is needed yet, but this aims for safety to allow testing
   of MT builds without interfering with other work.
 
 21st February 2013 - Gunter Folger (cmake-V09-06-04)
 - Updated dataset G4NEUTRONXS 1.3 ( previous was not yet released)
 
 13th February 2013 - Gunter Folger (cmake-V09-06-03)
 - Switch to G4NEUTRONXS 1.3
 
 12th February 2013 - Ben Morgan (cmake-V09-06-02)
 - Modules/Geant4MakeRules_cxx.cmake : Revert default CXX flags for GNU
   (and clang) compilers to non-MT versions. Leave MT flag set as commented
   out line for future reference, although MT will be optional.
 
 11th February 2013 -  Pere Mato  (cmake-V09-06-01)
 - Modules/Geant4TestDriver.cmake : increased the timeout safety to 120
   seconds. This is to avoid having a timeout in a test without having
   the time to write the output.
 
 18th December 2012 -  Ben Morgan       (cmake-V09-06-00)

   and "XXChannel.cc" names to false positives. These names appear
   in processes/hadronic/models/cascade/cascade/sources.cmake as
   comments, but the current regex picks them up. This is a temporary
   fix as longer term solution is to update regex to not match
   comments!
 
 21st November 2012 - Ben Morgan        (cmake-V09-05-74)
 - Templates/Geant4Config.cmake.in : Fix setting of Geant4 DEFINITIONS
   INCLUDE_DIRS and LIBRARIES so that multiple calls to find_package

   insert or append to these variables as needed. Duplicates
   are removed from the final list.

 13th November 2012 - Ben Morgan
 [BUGFIX #1290, #1328]
 - Templates/geant4-config.in : Add support for G3ToG4 library. Add
   CLHEP library to link line using output from clhep-config.
   Replace explicit -I@VAR@ flags with pure @VAR@ variables for
   each include path that may be filtered out if it is in the
   compiler's default search path.
 - Modules/Geant4ConfigureConfigScript.cmake : Set export variable
   for existence of G3ToG4. Implement function to return list of

   any header paths that we need to export but that appear in this list
   before creating export variables.
 
 13th November 2012 - Ben Morgan       (cmake-V09-05-68)
 - Modules/Geant4BuildProjectConfig.cmake : Copy FindXXX modules required
   by examples from source to build tree, and install them into a
   Modules subdirectory of GEANT4_CMAKE_DIR.
 - Templates/UseGeant4.cmake : Append path for FindXXX modules required
   by examples to CMAKE_MODULE_PATH. This is transparent across both
   the build and install trees.
 
 
 12th November 2012 - Ben Morgan       (cmake-V09-05-67)
 - Modules/Geant4MakeRules_cxx.cmake : Add -Qunused-arguments flag
   to compiler flags when running Clang. This is to finally suppress
   warnings when building tests, which CTest cannot filter out.
 
 
 9th November 2012 - Ben Morgan        (cmake-V09-05-66)
 - Resubmission of cmake-V09-05-64+cmake-V09-05-65. Former was
   rejected after clang warnings, which are now ignored by the
   CTest system. Latter passed Continuous builds without issue and
   only affects Windows systems.

 - Modules/Geant4InstallData.cmake : Increased default timeout to 1500s.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Redirect all cd commands
   to /dev/null as some cd implementations report change to stdout.
 
 March 30th, 2012 - Ben Morgan (cmake-V09-05-08)
 - Modules/Geant4InstallData.cmake : Add GEANT4_INSTALL_DATA_TIMEOUT cache
   variable to allow users to increase the download timeout on slow connections.
   Only available on CMake 2.8.1 and above.
 
 March 22nd, 2012 - Pere Mato (cmake-V09-05-07)
 - genwindef/LibSymbolInfo.cpp : filter the symbols giving problems when building G4clhep for Win64 (second attempt)
 
 March 22nd, 2012 - Pere Mato (cmake-V09-05-06)
 - genwindef/LibSymbolInfo.cpp : filter the symbols giving problems when building G4clhep for Win64
 
 March 7th, 2012 - Pere Mato (cmake-V09-05-05)
 - Modules/Geant4MakeRules_cxx.cmake : added link flag "-i-dynamic" to avoid link ICC warnings of the sort
                                       "warning: feupdateenv is not implemented and will always fail"
 
 March 6th, 2012 - Pere Mato (cmake-V09-05-04)
 - Modules/Geant4LibraryBuildOptions.cmake : matching "icc" in addition to "icpc" to detect Intel compiler
 - Modules/Geant4MakeRules_cxx.cmake : change ICC option from -Wnon-virtual-dtor to -Wno-non-virtual-dtor
 
 February 10th, 2012 - Pere Mato (cmake-V09-05-03)
 - Added function REFLEX_GENERATE_DICTIONARY() in FindROOT.cmake

 - Switch to G4EMLOW6.24
 
 December 13th 2011 - P. mato (cmake-V09-05-01)
 - Templates/UseGeant4_internal.cmake: Avoid prepending configuration tag for existing commands
 
 December 6th 2011 - B.Morgan (cmake-V09-05-00)
 - Modules/Geant4ToolchainBackwardCompatibility.cmake [BUGFIX #1265]: Added
   setting of expansion variable needed to prepend path with G4WORKDIR path.
 - Templates/geant4make-skeleton.in [BUGFIX #1265] : Added expansion variable for
   path setup to G4WORKDIR directory for executables.
 - Templates/geant4-env-skeleton.in [BUGFIX #1265] : Added needed '@' symbol
   to end of GEANT4_TC_SHELL_PROGRAM used as shbang.
 
 
 November 30th 2011 - B.Morgan (cmake-V09-04-41)
 - Modules/Geant4LibraryBuildOptions.cmake : Commented out
   GEANT4_BUILD_GRANULAR_LIBS option to restrict these builds for 9.5. Current
   granular build is not tested and broken in several places, so we want to
   prevent its use for now.
 
 November 29th 2011 - B.Morgan (cmake-V09-04-40)
 - Modules/Geant4InterfaceOptions.cmake : Added ability for Mac to concurrently
   build mixed Qt and X11 OpenGL driver. Xt library adde to X11 libraries, but
   only on Mac when Xm is built. Linking Xt on Linux causes runtime errors.
 - Templates Geant4Config.cmake.in : Fixed bug that prevented OpenInventor
   library being appended to output when vis_all was set.
 
 
 November 24th 2011 - B.Morgan (cmake-V09-04-39)
 - Modules/Geant4InstallData.cmake : Updated data library versions
   G4NDL -> 4.0
   RadioactiveDecay - > 3.4
   Added GEANT4_ADD_FEATURE reporting for data and example code install.
 
 
 November 23rd 2011 - B.Morgan (cmake-V09-04-38)
 - Modules/Geant4LibraryBuildOptions.cmake : Marked GEANT4_ENABLE_TESTING and
   GEANT4_BUILD_EXAMPLES options as advanced because these are for developers and
   system testing only.
 - Templates/geant4-env-skeleton.in (NEWFILE) : New shell skeleton file for core
   environment setup of geant4, just PATH, (DY)LD_LIBRARY_PATH and data libraries
   if installed.
 - Templates/geant4-environment-skeleton.in : RENAMED -> geant4make-skeleton.in
 - Templates/geant4-environment-skeleton.in : Added expansion variable to handle
   G4WORKDIR setup. Added expansion variables for data library setup.
   Added expansion variable to provide a self location block.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added a function to
   conditional set environment variables. Added setup of G4WORKDIR.
   Added setup of data library variables if they've been installed.
   Added self location capability so that scripts can find themselves and
   consequently locate library and include directories relative to the determined
   location.
   Moved installation of of backwared compatible toolchain files to a directory
   named 'geant4make' under the main data directory. This helps to partition the
   setup script and gmk files into their own, isolated location.
   Configure new 'geant4.(c)sh' setup script from geant4-env-skeleton.in file.
 - Modules/Geant4InstallData.cmake : Set name of list holding dataset information
   to GEANT4_DATASETS just to mark it as usable elsewhere. Added environment
   variable name to end of dataset information strings to help in setting them up
   in configuration of shell scripts.
   Marked GEANT4_INSTALL_EXAMPLES option as advanced.
 
 
 November 22nd 2011 - B.Morgan (cmake-V09-04-37)
 - Templates/Geant4Config.cmake : Added 'ui_all' and 'vis_all' components to
   allow simple selection of all available UI and Vis components.
 
 
 November 18th 2011 - P.Mato (cmake-V09-04-36)
 - Modules/Geant4CTest.cmake : Added some protection if GEANT4_DATA_DIR not defined
 
 November 16th 2011 - B.Morgan (cmake-V09-04-35)
 - Templates/geant4_validate_sources.cmake.in : Added two VRML icc files
   to false positive list. These are in VRML's src/ directory for internal
   use only.
 
 November 16th 2011 - G.Folger (cmake-V09-04-34)
 - Modules/Geant4InstallData.cmake: correct data file name
 
 November 15th 2011 - G.Folger (cmake-V09-04-33)
 - Modules/Geant4InstallData.cmake: update data libraries version for 9.5
 
 November 8th 2011 - B.Morgan (cmake-V09-04-32)
 - Templates/Geant4Config.cmake.in [BUGFIX #1196, #1261]: Added support for
   G4OpenInventor as a component, named 'vis_openinventor'. Prtected inclusion of
   Geant4LibraryDepends file by test on a variable Geant4_LIBDEPS_LOADED so that
   multiple calls to the config file from find_package are possible. This allows
   option selecting of the components. NB Full Inventor build requires tag
   openinventor-V09-04-02).
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added support for
   configuration of OpenInventor environment variables in
   geant4-environment-setup scripts.
 - Templates/geant4-environment-skeleton.in : Added support for OpenInventor
   environment variables needed by old Makefile toolchain. At present, OIVHOME is
   not set, as the Geant4 public interface should not need this.
 - Modules/Geant4ConfigureConfigScript.cmake : Added support for configuration
   of OpenInventor feature.
 - Templates/geant4-config.in : Added support for OpenInventor feature.
 - Modules/Geant4InterfaceOptions.cmake : Added support for OpenInventor, with
   new CMake option GEANT4_USE_INVENTOR to enable build. On Unix platforms, X11
   and Xm are also searched for as these are used in Geant4's Inventor module.
 - Modules/FindInventor.cmake (NEWFILE) : Find module for Inventor, adapted from
   post on CMake mailing list by Jan Peciva. Tested against Coin3d
   implementation.
 
 
 November 4th 2011 - B.Morgan
 - Modules/Geant4ConfigureConfigScript.cmake : Added setup of installed script
   to use self location functionality in geant4-config when installation is
   relocatable.
 - Templates/geant4-config.in : Added capability for script to self locate
   itself. The technique is to fully resolve any softlinks to the script file
   itself using readlink, but with workarounds because the '-f' option to
   readlink is not available on all platforms. No attempt is made to resolve
   any softlinks in the path elements or to replace occurrence of '.' or '..'.
   However, the algorithm has been tested in several softlinking situations
   and should cover everything but real corner cases... The result of the
   resolution is the diectory in which the script resides. This can be used
   later in the script as necessary.
 
 
 November 2nd 2011 - B.Morgan (cmake-V09-04-31)
 - Modules/Geant4InstallData.cmake : Bumped version of G4EMLOW library to be
   installed from 6.22 -> 6.23.
 
 
 November 2nd 2011 - B.Morgan (cmake-V09-04-30)
 - Modules/Geant4BuildModes.cmake : Reverted file to revision 51604
   (cmake-V04-04-28 tag) which removes the TestReleaseDebug mode.
 - Modules/Geant4MakeRules_cxx.cmake : Reverted file to revision 52696
   (cmake-V09-04-28 tag) which removes the TestReleaseDebug mode. This reverts
   TestRelease to having platform dependent flags, specifically there is no
   optimization on Apple.
 - Modules/geant4-config.in : Fixed typo error that used incorrect name for
   CMake supplied variable Geant4_VERSION, preventing correct expansion.
 - Modules/Geant4ConfigureConfigScript.cmake : Tidied up indenting to standard
   two space format. Added skeleton setup for making script relocatable in
   the Install Tree.
 
 
 October 11th 2011 - B.Morgan
 - Templates/Geant4Config.cmake.in [BUGFIX #1253] : Jean Jacquemier reported
   a problem when building applications using a pure static build of Geant4.
   This was traced to incorrect list syntax in Geant4Config.cmake, as detailed
   in the above Bug Report #1253. The fix is to remove the quotes around the
   list as these cause it to be represented as one single string.
 
 
 October 10th 2011 - B.Morgan (cmake-V09-04-29)
 - Modules/Geant4ValidateSources.cmake (NEWFILE) : Module to configure the
   geant4_validate_sources.cmake.in and create a custom 'validate_sources'
   target which runs the resulting configured script.
 - Templates/geant4_validate_sources.cmake.in (NEWFILE) : CMake script that
   locates all sources.cmake files in the Geant4 source tree, parses them to
   extract all listed sources/headers and compares that list with sources and
   headers on disk. Any mismatches whether files listed in sources.cmake and no
   longer on disk, or files on disk but not listed in sources.cmake, are
   reported. If any mismatches are found, the script will fail with FATAL_ERROR,
   though it will not do so until the whole tree has been scanned to ensure all
   mismatches are located. It ignores certain files that are known to cause
   mismatch detection but which are no longer part of the Geant4 CMake build.
 
 
 October 6th 2011 - B.Morgan (cmake-V09-04-28)
 - Modules/Geant4BuildModes.cmake : Added TestReleaseDebug mode to
   CMAKE_BUILD_TYPES and CMAKE_CONFIGURATION_TYPES.
   NB: Diaganosed problem reported by Pere, whereby added modes were not
   appearing in VS. This is likely because CMAKE_CONFIGURATION_TYPES is set
   *after* the project(...) call: http://www.itk.org/Bug/view.php?id=6788
   Will fix after new modes are confirmed.
 - Modules/Geant4MakeRules_cxx.cmake : Split TestRelease mode into two,
   TestRelease, which is optimized and has debugging symbols, and
   TestReleaseDebug, which has debug symbols only. Both still use
   G4DEBUG_VERBOSE and G4FPE_DEBUG definitions.
 
 
 October 4th 2011 - P. Mato (cmake-V09-04-27)
 - Modules/Geant4TestDriver.cmake: Fix to allow an empty command
 
 October 4th 2011 - P. Mato (cmake-V09-04-26)
 - Modules/FindXercesC.cmake: Added xerces-c_3 as a possible name for libraries (for windows)
 
 September 30th 2011 - P. Mato (cmake-V09-04-25)
 - Modules/Geant4MakeRules_cxx.cmake: Fixed debug flag to -Zi for Visual C++
 
 - Modules/Geant4CTest.cmake: Moved from tests/CMakeLists.txt the logic to
   construct the GEANT_TEST_ENVIRONMENT with data file locations to be useful
   for benchmarks tests.
 
 September 29th 2011 - B. Morgan (cmake-V09-04-24)
 - Modules/Geant4OptionalComponents.cmake : Removed enabling of Fortran language
   when G3toG4 is enabled. Gunter Folger reported problems with obtaining correct
   Fortran setup, so we disable this since we don't actually compile the rztog4
   app at present. A change has also been made in the top level CMakeLists.txt
   so that the Make rules initialization for Fortran is no longer set up.
 
 
 September 16th 2011 - B. Morgan (cmake-V09-04-23)
 - Templates/Geant4Config.cmake.in : Addition of G4VIS_USE and G4UI_USE to list
   of definitions has been made conditional on the existence of the variables
   G4VIS_NONE and G4UI_NONE. If those variables are set, e.g. via -DG4UI_NONE,
   the corresponding compile definition will not be set. This gives
   requested behaviour, but as before this is a temporary hack.
 
 
 September 16th 2011 - B. Morgan (cmake-V09-04-22)
 - Templates/Geant4Config.cmake.in : Added G4VIS_USE and G4UI_USE to list
   of core compile definitions. This is seemingly needed to support test
   building, but should only be seen as a temporary fix. These variables
   should be set at the application level.
 
 
 September 15th 2011 - P. Mato (cmake-V09-04-21)
 - Templates/UseGeant4_internal.cmake: Fixed a bug affecting tests on Windows.
 
 August 16th 2011 - P. Mato (cmake-V09-04-20)
 - Templates/UseGeant4_internal.cmake: Added support for tests on Windows with
   NMake and Visual Studio.
 
 - Modules/Geant4TestDriver.cmake: Avoid the use of ':' as separator since is used
   already in the drive letters on Windows.
 
 August 16th 2011 - P. Mato (cmake-V09-04-19)
 - Modules/FindROOT.cmake : Added function ROOT_GENERATE_DICTIONARY() to facilitate
   the generation of ROOT dictionaries
 
 - Modules/Geant4CTest.cmake (NEWFILE): Place for the configutation of CTest.
 
 - Modules/Geant4TestDriver.cmake: Added the pre- and post-commands for tests. This
   was neeed to preform some initial cleanup of post processing on some tests.
 
 - Templates/UseGeant4_internal.cmake: Changed the function GEANT4_ADD_TEST() to
   make use of the pre- and post-commands.
 
 August 16th 2011 - B.Morgan (cmake-V09-04-18)
 - Templates/UseGeant4.cmake : Fixed error is use of get_filename_component
   to locate internal use file.
 
 
 August 10th 2011 - B.Morgan (cmake-V09-04-17)
 - Modules/Geant4BuildProjectConfig.cmake : Added copy of UseGeant4_internal
   file to build tree, but do not install it.
 
 - UseGeant4.cmake : Factored out internal only macros into UseGeant4_internal
   module. Added optional inclusion of that module, which will only happen in the
   build tree.
 
 - UseGeant4_internal.cmake (NEWFILE) : Added to hold CMake code only needed
   by 'use' of Geant4 inside Geant4 itself, e.g. unit and validation tests.
   This is done to fix a bug reported offline by Alberto Ribon, where including
   UseGeant4.cmake fails due to an unfound custom CMake module. The functions
   like GEANT4_ADD_TEST use extra functionality which is located in custom CMake
   modules. Whilst these modules could be installed, this adds unneeded
   complexity to the use of Geant4 and may also clash with CMake itself. Also,
   the functions needing the modules are not intended for use by users, so are
   factored out into this build tree only module.
 
 
 August 3rd 2011 - B.Morgan (cmake-V09-04-16)
 - Modules/Geant4MakeRules_cxx.cmake, Modules/Geant4BuildModes.cmake :
   Moved setting of initial values for TestRelease and Maintainer mode compiler
   flags to make rules override file. Values are now set based on compiler and
   platform, as G4FPE_DEBUG option should only be used for GNU compiler, and
   with non-optimized code on Mac OS X (information from Gunter Folger).
   Geant4BuildModes uses initial values as input to cache value, so variables
   can be reset from the command line and within the cache interfaces if
   needed.
 
 - Modules/Geant4BuildProjectConfig.cmake : Re-added WIN32 guard on export of
   the G4LIB_BUILD_DLL definition.
 
 
 July 29th 2011 - B.Morgan (cmake-V09-04-15)
 - Modules/Geant4InstallData.cmake : Corrected URL for use in downloading data
   to use direct URL. Original URL redirects, which early 2.8 iterations of
   CMake appear not to like.
   Use .tar.gz of RadioactiveDecay as this is available and cheaper to download.
   Added use of PREFIX in ExternalProject so that all EP directories are
   created under a single 'Externals' directory. This is simply to keep the
   build tree nicely organized. The data still appear in the data/ subdirectory
   of the build directory, so this should not affect usage by tests.
 
 
 July 29th 2011 - P. Mato
 - Modules/CMakeMacroParseArguments.cmake : updated to the version exiting in CMake 2.8.5
 
 - Modules/Geant4MacroLibraryTargets.cmake, Modules/Geant4MacroDefineModule.cmake,
   Modules/Geant4MacroDefineModule.cmake : Adjusted to the new CMakeMacroParseArguments.cmake
 
 - Templates/UseGeant4.cmake : Removed installs included in GEANT4_LIBRARY and
   GEANT4_EXECUTABLE macros and fixed comments.
 
 
 July 28th 2011 - B. Morgan (cmake-V09-04-14)
 - History : Added note on preferred format of entries.
 
 - Modules/Geant4InstallData.cmake : Added guard on option and install of data so
   that this is only available on CMake >= 2.8 due to use of ExternalProject.
   (NB: Usage still broken, probably due to tar formats (CMake 2.8.1).
 
 - Modules/UseGeant4.cmake : Forced all CXX flags to use those used to build
   Geant4 [BUGFIX #1227]. Neatified and commented internal functions for
   library/exe/test builds. Added WARNING message if GEANT4_ADD_TEST is used
   outside of the Geant4 project. Corrected(?) include of
   CMakeMacroParseArguments (MIGHT BREAK GEANT4_XXX FUNCTIONS IN UseGeant4).
 
 - Modules/Geant4CPackBase.cmake : Added TBZ2 and ZIP types back into list of
   source package generators. Neatified the generation of the README file.
   Neatified and commented new component build commands.
 
 - Modules/Geant4MacroLibraryTargets.cmake : Corrected setting of
   INSTALL_NAME_DIR for library targets [BUGFIX #1231].
 
 - Templates/geant4-config.in : Added G4analysis library to default list of
   libraries.
 
 - Templates/Geant4Config.cmake.in : Added G4analysis library to Geant4_LIBRARIES
   variable. Always added for now rather than as an optional component.
 
 
 July 27th 2011 - P. Mato
 - Added the downloading and installation of Geant4 Data files if the option
   GEANT4_INSTALL_DATA is set. Modified Modules/Geant4InstallData.cmake
 - Initial version of CPack configuration for binaries.
   Modified Modules/Geant4CPackBase.cmake and added Templates/CMakeCPackOptions.cmake.in,
     Templates/g4_small.gif
 - Initial set of files needed for testing with CTest.
   Added Modules/FindROOT.cmake, Modules/Geant, Geant4TestDriver.cmake
   Added options GEANT4_ENABLE_TESTING, GEANT4_BUILD_EXAMPLES in
     Modules/Geant4LibraryBuildOptions.cmake
   Inherit CMAKE_MODULE_PATH in tests. Modified Modules/Geant4BuildProjectConfig.cmake,
     Templates/Geant4Config.cmake.in
   Added convenient macros to Templates/UseGeant4.cmake
 
 
 July 5th 2011 - G.Folger  (cmake-V09-04-13)
 - Modules/{Geant4LibraryBuildOptions,Geant4BuildProjectConfig}.cmake:
    protect setting of G4LIB_BUILD_DLL to happen on WIN32 only.
     (Affected examples/.../olap, which was built without this flag,
      and failed to link)
 
 July 5th 2011 - B. Morgan (cmake-V09-04-12)
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added support for
   setting GDML/Xerces variables as needed.
 - Templates/geant4-environment-skeleton.in : Added unsetting/setting of
   G4LIB_USE_GDML and XERCESCROOT. These are needed to help the automated builds
   of examples in the old toolchain. XERCESCROOT uses the value of
   XERCESC_INCLUDE_DIR with one directory level stripped off the end. This
   is not 100% foolproof if an odd XercesC install is used, but should cover
   the vast majority of cases.
 
 June 29th 2011 - B.Morgan (cmake-V09-04-11) (In geant4-09-04-ref-06)
 - INSTALL.g4cmake : Added warning about ensuring consistent compiler flag
   sets between build of Geant4 and build of user application.
 - Templates/UseGeant4.cmake : Added setting of all CMAKE_CXX_FLAGS_XXXX
   variables with appending of Geant4 recommended flags, and filter out
   any duplicate flags. Adding warning in documentation about this.
 
 June 23rd 2011 - B.Morgan (cmake-V09-04-10)
 - INSTALL.g4cmake : Added note on possible issues when building Windows
   applications using Windows 7 + VS2010 Express.
 - Templates/UseGeant4.cmake : Fixed idiotic typo error in globbing expressions
   inside file(GLOB_RECURSE).
 
 June 23rd 2011 - B.Morgan (cmake-V09-04-09)
 - INSTALL.g4cmake : Added in missing data library package names. Added
   note in Known Issues on Mac warnings from ld due to duplicate dylibs
   (the overlinking issue as it appears on Mac).
 - Modules/Geant4MacroLibraryTargets.cmake : Added setting of INSTALL_NAME_DIR
   target property to shared libraries (only affects Mac OS X) to final
   install location of libraries. This prevents "image not found" errors when
   building an app against Geant4 (you don't need DYLD_LIBRARY_PATH set).
   CMake *should* build the dylibs with the headerpad_max_install_names flag
   so that bundling the Geant4 libraries into an app should work (you can
   repoint the app to use the bundled libraries).
   N.B. THIS IS LIKELY TO AFFECT USAGE OF CPACK LATER ON!
 - Templates/UseGeant4.cmake : Fixed error in use of file(GLOB_RECURSE) so
   that globas are done only under the current source directory.
 
 June 22nd 2011 - B.Morgan (cmake-V09-04-08)
 - INSTALL.g4cmake : Finalized with description of using the three toolchains
   to build Geant4 applications.
 - Modules/Geant4ConfigureConfigScript.cmake : Updated with patch from Pere
   Mato Vila to export use of internal CLHEP to script when used. Also upgraded
   to export details on Motif. Script is now generated for both the build and
   install trees. On CMake >= 2.8, the build tree script is made executable.
 - Templates/geant4-config : Updated with patch from Pere Mato Vila to use
   internal CLHEP, plus upgrades to provide easier setting of third party paths,
   compile defintions and libraries. Added motif feature, and changed main
   prefix, lib and include directory variable replacement to that the script
   can be used form the build directory as well.
 - INSTALL.g4cmake : Updated with new guides on building user applications
   using CMake and GNU make.
 - Templates/Geant4Config.cmake.in : First full implementation with most
   features in place. Provides version and component checking. Setting of
   components features quite a bit of boilerplate code and a reasonable degree
   of in module processing. TODO : Investigate clean up and better
   modularization.
 - Templates/UseGeant4.cmake : NEW FILE : Provides a simple CMake module which
   users can include to setup the build of a basic Geant4 application without
   needing to know too many details. Sets definitions, include directories and
   compiler flags. Provides a simple macro to collate sources in an old style
   Geant4 Example, with documetation on usage in the file.
 - Modules/Geant4BuildProjectConfig.cmake : Set needed variables for export to
   Geant4Config.cmake script.
 - Modules/Geant4MakeRules_cxx.cmake : Added -DXPNET and
   -D_CRT_SECURE_NO_DEPRECATE to MSVC flags to make these exactly the same as
   used on old makefile system.
 - Modules/Geant4LibraryBuildOptions.cmake : Added definition G4LIB_BUILD_DLL
   needed to define import/export correctly. Done globally.
 - INSTALL.g4cmake : Fleshed out further.
 - Templates/Geant4Config.cmake.in : Fleshed out documentation with extra notes
   to help development.
 - Modules/Geant4BuildProjectConfig.cmake : Added extra comments
 
 June 21st 2011 - B.Morgan (cmake-V09-04-07)
 - Modules/Geant4BuildProjectConfig.cmake : Added section for collecting
   variables to be exported to the configuration files. Rationalized config of
   Build and Install Trees so that these sections have the same structure.
 - Templates/Geant4Config.cmake.in : Updates with documentation, debugging
   option and some improved setting of definitions. Still a skeleton though.
 - Modules/Geant4InterfaceOptions.cmake : Removed reset of OpenGL variables on
   Win32 because this seems to prevent proper refind of the variables. Since we
   expect to be able to use Qt and OpenGL concurrently on Win32. This *should*
   be o.k.
 - INSTALL.g4cmake : Added extra information on using Visual Studio.
 - Modules/Geant4ToolChainBackwardCompatibility.cmake : Removed setting of
   G4ORDPARAMTABLE as this is no longer needed.
 - Templates/geant4-environment-skeleton.in : Removed setting of G4ORDPARAMTABLE.
 
 
 June 20th 2011 - B.Morgan (cmake-V09-04-06)
 - Modules/Geant4InterfaceOptions.cmake : Corrected typographic error in option
   test for enabling Qt on Non-Apple platforms.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added Geant4 to
   end of G4INCLUDE path for install tree in line with changes to
   Geant4InstallDirs.
 - Modules/Geant4MacroLibraryTargets.cmake : Added Geant4 to end of installation
   destination for headers in line with changes to Geant4InstalDirs.
 - Modules/Geant4InstallDirs.cmake : Removed Geant4 from INCLUDEDIR to better
   reflect standard practice. The Geant4 tag is now added to the destination in
   the install commands for headers.
 - Modules/Geant4OptionalComponents.cmake : Automatically use GDML if user
   supplies XERCESC_ROOT_DIR argument.
 - Modules/Geant4InstallData.cmake : NEW FILE : Refactored installation of
   examples from top level CMakeLists.txt into this file. Also provided stub
   option for installation of data libraries. We don't implement this yet
   because it appears to require some CMake 2.8 specific functionality and
   I haven't yet worked out how to reproduce this in 2.6.4.
 - INSTALL.g4cmake : Rewritten for updated CMake system with full documentation
   of variables. Provided sections for describing use of the three toolchains
   for building user applications, but not fully covered yet.
 
 June 20th 2011 - B.Morgan (cmake-V09-04-05)
 - Modules/Geant4LibraryOptions.cmake : On Unix platforms, set output directory
   for libraries to end in the 'SYSTEM-COMPILER' tag expected by the old
   toolchain. This allows the build tree to be used with the old toolchain.
   #BUGFIX - 1200 (PARTIAL)
 - Modules/Geant4OptionalComponents.cmake : Now ensures that the static versions
   of the internal G4clhep and G4expat libraries are used if geant4 is built
   completely static, otherwise dynamic libs will be used. This is not perfect
   but ensures builds will not fail.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Completely rewritten
   to use new geant4-environment-skeleton.in template. Provides full setup
   of environment from build and install trees, permitting developers to
   build applications directly using the build tree. Also adds all currently
   supported visualization/ui modules. Adds setting of the G4ORDPARAMTABLE
   variable to support this new resource file.
 - Templates/geant4-environment-skeleton.in : NEW FILE : Universal shell script
   skeleton for generating backward compatible environment variable setup.
   # BUGFIX - 1202
 
 June 17th 2011 - B.Morgan (cmake-V09-04-04)
 - Modules/Geant4ConfigureConfigScript.cmake
   Modules/Geant4ToolchainBackwardCompatibility.cmake : Updated to use new
   GEANT4_USE_RAYTRACER_X11 variable.
 - Modules/Geant4InterfaceOptions.cmake : Corrected type in resetting of OpenGL
   variables.
   Changed GEANT4_USE_RAYTRACERX -> GEANT4_USE_RAYTRACER_X11 to be in line with
   what's done for other drivers.
 
 June 17th 2011 - B.Morgan (cmake-V09-04-03)
 - Tagging : internal because this requires testing.
   Full support also requires tags:
    interfaces-V09-04-03
    opengl-V09-04-05
 
 - Modules/Geant4InterfaceOptions.cmake : Rewritten to enable correct switch
   between Qt and X11 based GUIs on Mac, with consistent changes in OpenGL
   location. Added in find_package for Motif. Added full option and find_package
   for locating OpenGL on Win32.
 - Modules/Geant4OptionalComponents.cmake : Imporved documentation of external
   CLHEP option. GEANT4_USE_SYSTEM_CLHEP made a standard option as it will
   likely be used a lot to begin with.
 
 June 16th 2011 - B.Morgan (cmake-V09-04-02)
 - Modules/Geant4LibraryBuildOptions.cmake : Default to building shared libraries
   on all platforms, but warn about possible link errors on MSVC when building
   both shared and static libs. Mark both library build options as advanced.
   Add warning about building granular libs as only for developers.
 - Modules/Geant4InterfaceOptions.cmake : Reverted to version from
   cmake-V09-04-01 because of poor logic.
 - Modules/FindCLHEP.cmake : UPGRADE WITH INTERFACE BREAK : Much simplified
   search structure which no longer relies on clhep-config. The user can supply
   a CLHEP_ROOT_DIR argument to point CMake to a specific installation. On UNIX
   clhep-config will be searched for under this root dir. CLHEP library and
   include path will be found under this root dir, or in the system paths.
   Version checking is also provided which follows the standard logic of
   CMake modules.
 - Modules/Geant4OptionalComponents.cmake : Option to use system CLHEP is
   now automatically set to ON if the user has supplied a CLHEP_ROOT_DIR
   argument. This simplifies the interface.
 
 June 15th 2011 - B.Morgan
 - Modules/Geant4InterfaceOptions.cmake : Added in option for enabling Xm (Motif)
   support with find_package for Motif headers/libraries.
   Use of Qt and X11 OpenGL have been made mutually exclusive on Mac OS X to
   prevent clashes between Framework OpenGL and X11 OpenGL.
   Added new stub option to build OpenInventor driver
   TODO: Add FindInventor module, check build of OpenInventor category.
   Added new stub option to build Win32 OpenGL driver.
   TODO: Add Win32 build to OpenGL category.
 - Templates/geant4-env.sh.in
   Templates/geant4-env.csh.in : Removed unsetting of data library environment
   variables.
   TODO : Add setting of these as an optional codeblock if data was installed
   as part of the Geant4 build.
 
 June 15th 2011 - B.Morgan (cmake-V09-04-01)
 - Modules/Geant4InterfaceOptions.cmake : Set QT_USE_IMPORTED_TARGETS on WIN32
   to stop errors when setting LINK_INTERFACE_LIBRARIES to a value containing
   the 'optimized' etc library link keywords. By default, FindQt4 will use
   these keywords...
   KNOWNISSUE: Using imported targets means that the Geant4Config.cmake file
   must regenerate these targets otherwise the link will fail.
 
 June 14th 2011 - B.Morgan
 - Modules/Geant4MacroLibraryTargets.cmake : Added build of DLL targets on
   WIN32 platforms. Export definition files are generated by genwindef from
   an archive library. If Geant4 is not built with archive libraries, a
   dummy, non-installed archive will be built an used.
   The structure largely follows that of GaudiPolicy.cmake from Pere Mato Vila.
 - Modules/Geant4LibraryBuildOptions.cmake : Added build of genwindef app
   on WIN32 platforms as an internal app, as per guidelines from
   GaudiPolicy.cmake from Pere Mato Vila.
 - Modules/genwindef/genwindef.cpp
   Modules/genwindef/LibSymbolInfo.hpp
   Modules/genwindef/LibSymbolInfo.cpp:
   NEW FILES to support generation of DLL .def files on WIN32 platform.
   Courtesy of Pere Mato Vila.
 - Modules/Geant4Wrapping.cmake : NEW FILE : Refactoring of options for
   Python wrapping to help in modularization. Python wrapping is not yet
   implemented in the CMake build, but this is where we'll set it up.
 - Modules/Geant4OptionalComponents.cmake : NEW FILE : Refactoring of options
   for CLHEP, Expat, ZLIB, GDML, G3TOG4 from top level CMakeLists.txt to
   help with modularization.
 - Modules/Geant4LibraryBuildOptions.cmake : NEW FILE : Refactoring of library
   build options from top level CMakeLists.txt, including global define flags,
   global vs granular library format and static vs shared builds.
 - Modules/Geant4MacroLibraryTargets.cmake : Ensure that when static targets
   are built, they are linked to Geant4 static targets.
   TODO: Do we want to make this the case also for external libraries (very
   difficult?)?
   KNOWNISSUE: G4global will always be linked to shared G4clhep if latter is
   built as will G4processes to shared G4expat. Not critical (well, shouldn't
   affect running or applications).
 
 June 13th 2011 - B.Morgan
 - Modules/Geant4CPackBase.cmake : Added to list of files to be excluded for
   source package so that .svn and top level tests directories are not added.
   Fixed source package generator so that .tar.gz, .tar.bz2 and .zip packages
   are created.
   Tidied up structure so that future changes are easier to add in a clear
   way.
 - Modules/Geant4InterfaceOptions.cmake : Removed accidently commited change
  of finding VTK as a test of find_package.
 
 June 10th 2011 - B.Morgan
 - Templates/geant4-config.in : Adapted to use new install directories as
   provided by Geant4InstallDirs as template parameters.
 - Modules/Geant4ConfigureConfigScript.cmake : Added support for new
   install directories defined in Geant4InstallDirs
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added support for
   new install directories defined in Geant4InstallDirs.
 - Modules/Geant4MacroLibraryTargets.cmake : Added support for install of
   libraries and headers to new install paths defined by Geant4InstallDirs.
   Added EXPORT to library targets so that they can be used by Geant4Config
   scripts.
   Added proper COMPONENT argument to install commands to correctly partition
   targets needed for Development and for Runtime.
   Appended each library target and include paths to global
   properties so these can be exported to Geant4Config file easily for use
   from the build tree.
 - Templates/Geant4Config.cmake.in : NEW FILE : Template versioning file
   for use by Geant4Config.cmake.
 - Templates/Geant4Config.cmake.in : NEW FILE : Template files for CMake
   config script for Geant4. VERY PRELIMINARY.
 - Modules/Geant4BuildProjectConfig.in : NEW FILE : Builds CMake Config scripts
   to allow external projects to use Geant4 from a build or install tree.
 - Modules/Geant4InstallDirs.cmake : NEW FILE : Adds a standard set of
   installation location based on the GNU set. Adapted from GNUInstallDirs
   provided with CMake 2.8, but cut down to only use directories needed by
   Geant4.
 - Modules/CMakeUninstallTarget.cmake : NEW FILE : Adds an 'uninstall' target
   to remove all items installed via the install command.
 - History: Corrected a couple of entries with incorrect year in the date.
 - Modules/Geant4InterfaceOptions.cmake: Set GEANT4_ADD_FEATURE for all
   UI/Vis options so that enabled options are reported at the end of
   configuration.
 
 
 May 25th 2011 - B.Morgan
 - Modules/Geant4InterfaceOptions.cmake : Added new GEANT4_USE_OPENGL_X11
   option to enable build of OpenGL library X11 component. If enabled, will
   search for X11 libraries (plus Xmu, which FindX11 doesn't do) and OpenGL.
   Also performed some cleanup of the Qt section.
 - Templates/geant4-env.sh.in : Added variable setting for OpenGL X11
 - Templates/geant4-env.csh.in : Added variable setting for OpenGL X11
 - Templates/geant4-config.in : Added needed reporting and flags setting for
   OpenGL X11 support.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added setting of
   variable needed to export the existence of OpenGL X11 in the geant4-env
   scripts.
 - Modules/Geant4ConfigureConfigScript.cmake : Added setting of variables
   needed to export OpenGL X11 existence and X11 flags to geant4-config script.
 
 
 May 24th 2011 - B.Morgan (cmake-V09-04-00)
 - *** All History for the CMake category will now be in this file ***
 - Templates/geant4-env.sh.in : Added variable setting for RayTracerX
 - Templates/geant4-env.csh.in : Added variable setting for RayTracerX
 - Templates/geant4-config.in : Added needed reporting and flags setting for
   RayTracerX support.
 - Modules/Geant4ToolchainBackwardCompatibility.cmake : Added setting of
   variable needed to export the existence of RayTracerX in the geant4-env
   scripts.
 - Modules/Geant4ConfigureConfigScript.cmake : Added setting of variables
   needed to export RayTracerX existence and X11 flags to geant4-config script.
