How does it compare speed wise with other solutions? Fast incremental
builds are a very nice thing to have. There have been a few discussions
on the sweng mailing list where CMake has been brought up and I don't
think I ever saw performance reports for it. Generally the attitude
there seems to be that Jam is best and KJam is better than that. How
does CMake compare?

I see.
