I didn't know this exists. You'd have to add a lot of directories, 
though, since it doesn't want to see the QML import path but the paths 
to the individual modules I guess.

If you have a solution in mind, feel free to push a change to 
https://codereview.qt-project.org and add me as reviewer. It would be 
nice to make this work.
