Hi, Jan Möbius ,
We finally knew  WITH_QWT  is preprocessor that is set in cmake files in each project.
We rebuilt the whole solution.
The building goes fine now; but Openflipper crushes when we run it.
We are sure it is deadly caused by the project referencing QWT.

We use QWT 6. It is the version recommended by your website;
Could you let us which QWT version you are using??

wuwu, a half day passed away, but we were still in the origin!!!!
