It happens during the "cmake run", but every "make run" re-runs cmake to
check for changes. Theoretically you don't have to re-run cmake ever again
after the first run, as it's handled automatically (and it's very fast,
thanks to the cache system).

I thought you'd say that, but don't be too selfish ;-) There are onother
people who like to build from VisualStudio and/or Xcode. It's certainly a
pro for possibly most of OpenSG's user base (I know it would around here).

Actually CMake is very relaxed in that sense. It does not separate the build
tree from the source tree as strictly as SCons does. At first we thought it
was one of its weaknesses, but now we don't really care. Qt's generated
files are created in the source tree by default. Fortunately it's easy to
get "make clean" to work and neatly clean the source tree.

Actually, I was talking about configuring "prerequisite" packages like Boost
and Qt ;)
With CMake you usually glob all header files and include them in the build
(so they are also included in VS/Xcode projects). It works fast and very
well for us. SCons dependency scanners are nice, but quite honestly, I was
glad to sacrify them in favour of much faster builds (and no problems so
far).
PS: remember that packaging and installation is MUCH MUCH better in CMake
;-)
Kind regards,
