Ask Alex, he wrote the include cache stuff, and it does make dependency
scanning amazingly fast.  I think the syntax is meant to be very fast to

Well, the intention is to work with existing build trees.  I just tried
generating a simple example project with 2.4 and then running CMake from
CVS on it.  Everything still rebuilds correctly (both with and without
building between the cmake runs).  Are you able to reproduce this if you
create a kdecore tree with cmake 2.4 and then run cmake HEAD on it again?
