I'd like to propose this patch to support side-by-side installation of osgQt built against both Qt4 and Qt5. This would greatly simplify the packaging task downstream in various Linux distros, since not all projects have made the transition to Qt5 and hence both osgQt-qt4 and osgQt-qt5 are needed. (And the same situation might occur again if and when Qt6 is released).
Having support upstream would be advantageous instead of every distro hacking in their own solution.
This proposed patch keeps the osgQt name for the Qt4 build, but adds a 5 (i.e. osgQt5) for the Qt5 build. This is consistent with Qt (i.e. libQtCore -> Qt4, libQt5Core -> Qt5). It adds qt5 to the name of the example executables as appropriate.
