As far as I am concerned, the solution of calling CMake -E explicitely
is good (when you have in mind that CMake is no longer running).

All in all, CMake is a good and powerful tool, but I find that the
documentation is lacking behind. More structure, more usage example,
more common cases would in my opinion really help the user experience.

On the other side, the mailing list is very reactive.
