The project() command in the top-level CMakeLists.txt was not specifying languages which default to enabling C and CXX. The googlemock and googletest project() commands were explicitly enabing both the C and CXX languages in their respective subdirectories, although all their source file are correctly identified as CXX and the C language is effectively never used. Enabling the C language forces CXX-only projects downstream that embed this repo (via FetchContent or add subdirectory) to detect a C compiler at configuration-time. This PR proposes to properly only enable the CXX language. Signed-off-by: Damien L-G <dalg24@gmail.com>
