I've spent some time to port Marble to Qt5 actually. Current state is that the 
QWidget version works fine with Qt5 (performs even better than the Qt4 one) but 
the plugin structure does still rely on QGraphicsItem which obviously doesn't 
play well with QtQuick >= 2.0.

We hope to tackle that one soonish. Any help is welcome.

I agree that there are some quirks, but if you don't need each and every 
feature I think there are good chances you'll be able to embed it in another 
application.
