Summary:                    Cannot use ccache when building cmake
Description: 
If have tried to bootstrap cmake using ccache and gcc by setting CC='ccache gcc'
and CXX='ccache g++' but it does not work and ccache is not used.

Steps to Reproduce: 
$ mkdir _build
$ cd _build
$ CC='ccache gcc' CXX='ccache g++' ../configure --prefix="$HOME/usr/stow/cmake"
--qt-gui --qt-qmake=/usr/bin/qmake --parallel=2 --verbose


Additional Information: 
I have attached the cmake_bootstrap.log. Apparently bootstrap understands CC and
CXX as a list so it first tries ccache alone as a compiler and then gcc alone.
Of course ccache alone fails to build the test program so gcc is picked up
instead of 'ccache gcc'.

I would suggest to add a --enable-ccache option to this script. I'll try to
write a patch.
