One really nice feature what I miss in cmake is the '-project' option 
from qmake. Basically it scans the current directory, adds all sources, 
headers and ui-files and creates a small .pro file out of it. It's a 
very convenient feature when you just want to compile a small test 
project. Creating an initial CMakeLists.txt from scratch takes much 
longer and therefore this is the only place where I use qmake (outside 
the qt sources)
Maybe this can be added - simply read the current directory and pass the 
files found to a template CMakeLists.txt to create the project type you 
want - I assume not all ant to get a Qt project when such a feature 
would be added to cmake... :)

Thx,
