[CMake] Execute command after project generation

[Petr Kmoch]

Hi Nicolas.

Last time I asked for something like that, it was rejected:
http://public.kitware.com/Bug/view.php?id=13020

But maybe the stance could change on that? After all, I don't think CMake
would want to cater for every possible postprocessing anyone needs. Perhaps
it could be considered if a big warning "May not be forward compatible" was
attached to it?
