Hi everyone
I encounter such an error when installing Geant4!
CMake Error: The source directory “/usr/local/include/geant4-build” does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
You shouldn’t be specifying your build directory as your source directory. You should specify the actual source directory (i.e., where did you unpack the Geant4 tarball?).
