Sounds fair enough to me, for now. I think I'll use CMake for a while
now and see if I run into trouble. My first impression is that I like it
- it seems to be more modern and adjusted for today's needs, compared to
the ancient autotools.

Btw, I've committed an updated CMakeLists.txt and moved files into
"drivers" subdir (just audio and midi drivers) and an "rvoice" dir (for
the voice renderer stuff) which will get more files in it soon.
