Thank you very much :-)
Would it be possible to apply it also to the 2.4 branch, but maybe keep it undocumented until it has proven its usefulness ?
I can test it on my machine, but it can get wider testing (KDE) only if it goes into the 2.4 branch.

Is it actually possible to query the cmake patch level from within cmake files ? The last time I tried it didn't work. From the second run on one can use CMAKE_CACHE_RELEASE_VERSION, but this is empty on the first run.
If this would be possible I could adjust the RPATH handling depending on the cmake version without requiring everybody to update his cmake.

Bye
Alex
