[CMake] Mixing up project language settings?

[Nicholas Braden]

If the new C++ components are built optionally, I would use
enable_language(CXX):
https://cmake.org/cmake/help/latest/command/enable_language.html

Otherwise, if the project will always need C++ support from now on,
amend the project() statement. In this case it doesn't matter whether
you add CXX or remove C, it is up to you aesthetically.
