CMake: copy clang and resource files only if necessary

Browse Source 
Uses a timestamp file in the build directory to detect when the input
changes using DEPENDS from add_custom_command.

Total copied files size sum up to more than 260 MB. This was copied at every
incremental build, even if nothing changed.

This leads to faster build, especially when the copied files are not
cached in RAM or when not using a SSD.
