[Development] Qt3D without Qml/QtQuick?

[Harald Vistnes]

Thanks Sean,

I had a look in qt3d/src/src.pro, but there already was a
qtHaveModule(quick) {} around the quick3d libs and I don't know where the
dependency on qtdeclarative is set. I'd be happy to provide a patch, but it
seems I don't know enough about the internal Qt dependency settings...
