Hi Bernd, If you application is using the osgQt library and this lib is linked to Qt4 then mixing the viability of mixing Qt5 libs in your application will be down to Qt4/5 compatibility, something I can't answer as I'm no Qt expert but I guess it's reasonable to assume that this could cause problems.
If you can't mix Qt5 and Qt4 within a single application then you'll either have to rebuild the OSG against Qt5 or avoid using components of the OSG that use Qt - primarily this is osgQt but there a few plugins use it too. Non of the core OSG libraries use Qt so fundamentally the OSG will be Qt agnostic, so I you avoiding osgQt and used your own OSG/WIndow integration or just used the OSG's osgViewer native windowing support you'll be fine.
