...and it would be even easier if it just works with the shipped version. 
People do complain if some software has too many requirements. It's easy to 
mess up your installation when installing your self compiled packages. CMake 
is probably one of the less problematic packages.

It would be nice if we would have some more people doing nightly builds:
Right now we have only one box, and this runs Linux.
Having more would help us with portability among supported OSs and also among 
different version of CMake :-)
The CMake guys try really hard to keep compatibility, so if we would have to 
require one exact version of CMake either we would be doing something wrong 
or the CMake devs would have done something wrong. Currently none of both is 
the case.

I'll wait till tomorrow evening whether there are serious objections (when 
requiring 2.4.3 there were serious complaints). If there are none, I'll 
announce that we'll require 2.4.5 starting in one week on Monday, March 19th.

So, if you somebody has objections, speak up now.

A short note on kde-core-devel whenever updating qt-copy is required would 
indeed be nice :-)

Not really :-P
And yes, having to recompile qt-copy does slow development down. Requiring 
more prerequisites to be recompiled more often slows it down more.

I don't want to break the build behind peoples backs and just silently force 
everybody to update.
