Hi Michael,

Well this is sort of what I was looking for, though I was hoping that it
would be possible to list any useful variable *before* running CMake.

Is there some kind of hook, e.g. 'cmake --custom-help', that can be used
to display project-specific help. The help text should be provided by
the developer, of course.

Best regards,
Marcel Loose.
