One really nice feature what I miss in cmake is the '-project'

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... :)
Sounds like a nice idea! Would certainly help beginners get up and
running quickly.
Does qmake figure out which libraries you're using, etc. or does it
just generate a barebones file that you have to fix up yourself if you
want to add external dependencies?
It's using QtCore and QtGui by default, the rest must be specified on
the command line: qmake -project QT += "widgets network"
will add the line 'QT += widgets network' to the pro file (*)
Therefore my idea with the template
cmake -project qt -modules widgets, network --> simple CMakeLists.txt
with Qt components core, gui, widgets, network
cmake -project c++ --> simple CMakeLists.txt without any Qt dependency
Or a simple helper script which creates the project file.
Thx,
Christian
