It's definitly the wrong place, but currently C++ and Qt support are melted 
together, and I haden't the time to split it up. It's a quick fix to solve 
the biggest things.

- The class generator should be getting more modular, that was the main 
problem.
- And there is no "qmake" configuration. Neither in project nor in the global 
configuration.

Many problems, and I already work with Qt4 and have no time left to fix all.
