Qwt and Qxt seem to be automatically built when MITK is built with Qt. There seems to be no way to disable Qwt and Qxt although there is no real dependency in the core and most modules (except QtWidgetsExt, diffusion, ToFUI).
Is there a possibility to disable Qwt and Qxt that I have missed? It should be possible to build MITK without these external projects.
