24 - You need to have built the persistency/gdml 25 - You need to have built the persistency/gdml module by having
25 set the -DGEANT4_USE_GDML=ON flag during the 26 set the -DGEANT4_USE_GDML=ON flag during the CMAKE configuration step,
26 as well as the -DXERCESC_ROOT_DIR=<path_to_x 27 as well as the -DXERCESC_ROOT_DIR=<path_to_xercesc> flag pointing to
27 the path where the XercesC XML parser packag 28 the path where the XercesC XML parser package is installed in your system.
