Created attachment 105562 [details] proper QtAV *detection* on Mac There is an error in FindQtAV.cmake: on Mac, the dependency is assumed to be present and installed in a single location. I cannot comment on the latter aspect but I can confirm that the digiKam build fails when you don't have QtAV installed (in the supposed location). I'm attaching a patch to fix that.
