Agree with this.

Your technique (use ls) is no better than file(GLOB) because either way
the logic is only run at CMake configure time which leads to CMake not
knowing when it needs to regenerate your build files.

The best practice (which I heartily recommend) is to hardcode the list
of files into your CMakeLists.txt.
