If *_COMPILER_ARG1 is set, then it shall be the compiler, and the value for CMAKE_<LANG>_COMPILER may be ccache, but could also be something else, e.g., distcc, etc.  Therefore, I don't see a clean way to check it.

However, newer versions of cmake have abandoned the *_COMPILER_ARG1 solutions and set CMAKE_<LANG>_COMPILER to the real compiler and use a new variable, CMAKE_<LANG>_COMPILER_LAUNCHER for ccache, distcc, etc..

So the solution is just to upgrade to the newest version of cmake if you want to use ccache, etc...
