Hmm, ok, I also don't know that much about packaging, but I'd like to mention 
that cpack which comes with cmake has improved a lot in cvs, which will 
become cmake 2.6 later this year.
cpack can now also create debian and RPM packages.
Projects which want to create packages with cpack need to set a bunch of 
variables and then include CPack. While this makes things ugly if you do this 
directly in the cmake files, you can of course split this into a separate 

If cpack is currently (as in cmake cvs) not good enough for us, I'd really 
like to have either a list of features we need to use it for kde packaging or 
even better feature requests/bug reports in the cmake bug tracker, component 

E.g. it would make creating user/development packages easy (if we extend our 
install commands) and we would have an all-in-one solution.
