CMake: Set the correct variables for ccache. 

As the RULE_LAUNCH_COMPILE documentation says,

"Note: This property is intended for internal use by ctest(1). Projects
and developers should use the <LANG>_COMPILER_LAUNCHER target properties
or the associated CMAKE_<LANG>_COMPILER_LAUNCHER variables instead."
