With Geant4 10.0 no longer being supported or tested (it is ~7 years since the last patch), it’s not going to be easy to provide support here. All I can imagine is that the CMake version in use is parsing the information in those files incorrectly. Depending on what that version is, you might try using an older CMake version, such as 2.8.12, or 3.1-3.3.
