Sure. See our old build scripts in BUILD/* there's ccache all over.
They're from autotool-times, but I believe Monty is still using them.
So one can use ccache with cmake.

Our build scripts to CC='ccache gcc' CXX='ccache g++'.
That's actually not a good idea, a compiler with the space in the middle
kind of works in cmake (there's special support for this use case), but
I've hit rough edges.

But using ccache symlink wrappers should generally work with no problems
at all. I remember trying that and it worked.

Try CC=gcc CXX=g++ before running cmake.

I don't know exactly in what locations cmake is using for a compiler and
why it doesn't pick up your symlinks automatically.
