I guess this doesn't make enough sense because it is only 4.5 where 
setGraphicsSystem exists:

      get version from aboutQt
      if version >= Qt 4.5
         if QT_GRAPHICSSYSTEM does not exist
            pick highest rendering in order of
            "openvg", "opengl", "raster", "native"
         else
            setGraphicsSystem(QT_GRAPHICSSYSTEM);
         endif
      endif

The version test could be dropped.

If one doesn't want to force the upgrade of Qt then:

#if QT_VERSION >= 0x040500
    if QT_GRAPHICSSYSTEM does not exist
       pick highest rendering in order of
       "openvg", "opengl", "raster", "native"
    else
       setGraphicsSystem(QT_GRAPHICSSYSTEM);
    endif
#endif
