QtCreator and OpenCV, .dll missing

[schludy]

It is something wrong with OpenCV linking, not with your project.

Thanks for the hint, that led me to the solution and this page:

Turns out, using opencv-superpack.exe and the .dll's in that folder is not doing the job.
Solution: Build OpenCV again, using cmake (step by step here: http://opencv.willowgarage.com/wiki/MinGW)

Now it's running, with only changing the first LIB to the new build!
Thanks again!
