Disable RDI CCCAHE if cmake version great that 3.20.0 (#8262)

> For the Makefile Generators, source dependencies are now, for a > selection of compilers, generated by the compiler itself. This doesn't work in RDI CCACHE which generates its own compiler induced dependencies. There is a variable CMAKE_DEPENDS_USE_COMPILER to revert to old behavior but that does not work. This PR disables RDI CCACHE if CMake is not compatible. Signed-off-by: Soren Soe <[email protected]>
