Hi,
I've noticed that when using a prebuild package of cmake, the --help options
don't work because they try to read the documentation from the source
directory rather than the installed directory.
Below is my patch to fix this. Its made against the "KDE cmake" snapshot but
looking at cmake CVS, the code seems still the same.
