0003 # --------------------------------
0004 #
0005 # Due to use of C++17 features in visualization on Windows, Geant4 requires
0006 # use of VS 2017 update 3 or newer. CMake 3.10 and higher support this out
0007 # of the box, but with our minimum requirement of 3.8, we add this shim
0008 # to:
0009 #
0010 # 1) Check the version requirement
0011 # 2) Set the compile flags/features when using CMake < 3.10
0012 #
