For C++ projects, this heuristics may work:

- Find the C++ compiler.

- Unless the user asked for a specific C compiler, chose it depending on
  the C++ compiler found (c++ for cc, g++ for gcc, clang for clang++,
  etc)

Also, I'll propose that if CMake fails to find a matching C compiler on
the second step above, the process shall error out.
