Summary0011707: Cannot use ccache when building cmake
DescriptionIf 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 InformationI 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.

Oups. My patch 'bootstrap-enable-ccache.patch' that accurate in the usage message.

Now it is:
Enable ccache when bootstrapping and building cmake.

But it should be:
Enable ccache when building cmake.

alternatively, simply symlink ccache to ./gcc and ./g++ and then set CC=$PWD/gcc and CXX=$PWD/g++.

And if you're using Ubuntu/Debian and installed ccache using the package manager, use CC=/usr/lib/ccache/gcc and CXX=/usr/lib/ccache/g++ directly. If using CentOS/RHEL/Fedora/OpenSUSE/..., replace the /usr/lib with /usr/lib64 if running a 64-bit operating system. Other operating systems will have similar facilities.
