ronak69 d720fb8845 CMake: Set CMAKE_COLOR_DIAGNOSTICS to ON for colored diagnostics
This patch removes the explicit compile flag that only works for g++
(`-fdiagnostics-color=always`; clang++ needs `-fcolor-diagnostics`) and
uses CMake's built in variable that can control color output.

Now both compilers should output colored diagnostics.
