I'm not sure what's wrong in your case
but I did successfully used ccache + gcc/g++ and CMake 2.4.7
with no problem at all.

I did not export GCC= etc..
and then run cmake
but I did:

CC="ccache gcc" CXX="ccache g++" cmake

which works fine for me.
I did that because there is an example on the CMake wiki
page for "distcc"
see:
http://www.cmake.org/Wiki/CMake_Useful_Variables
then search distcc.

I think your problem comes from the fact that you've tried
to set GCC="ccache gcc".
I think you shouldn't set GCC but only

CC="ccache gcc"
CXX="ccache g++"

then it should works.
Could you try this?
