[Interest] qmake: questions regarding huge projects

[Bo Thorsen]

Hi Rainer,

Sounds to me like you want to switch to cmake instead. That has a lot 
better support for dependencies between subprojects than qmake. And for 
a project of this size, I would expect you have some fancy build stuff 
in there as well, and qmake is usually too simple for it.

Bo.
