Importing from Github PR: https://github.com/Geant4/geant4/pull/1 The FindCLHEP module can be removed due to CLHEP having a CLHEPConfig.cmake file. However, this is only "feature complete" (i.e. imported targets provide correct usage requirements) from CLHEP 2.3.3.0. Patches to Geant4 versions that required CLHEP < 2.3.3.0 will require workarounds.
Fixed in cmake-V10-03-11. This only resolves the issue for CLHEP 2.3.3.0 and higher as noted earlier.
