Oops.  Guess I haven't done enough of these to remember how I did them.

I don't think that follows.  The format for -D is actually well
documented in cmake.html.  Just because people don't do this a lot
with CMake, and don't know things off the top of their heads, doesn't
mean the method is wrong, broken, or needing improvement.

I think this is purely a marketing issue.

Anyways, people can feel free to put a feature request in the bug
tracker.  I don't see any tremendous harm in allowing --enable-* style
commands.
