CMake: Error out if ccache is requested but not found

Browse Source 
Before, we would just issue a warning which is likely to get overlooked
in CMake's output.  Also, the configure summary would report "Using
ccache ... yes" but CMAKE_<LANG>_COMPILER_LAUNCHER stays unset, which is
inconsistent.

Make QT_USE_CCACHE=ON and missing ccache a hard error.
