As reported on Hypernews: http://hypernews.slac.stanford.edu/HyperNews/geant4/get/installconfig/1394.html the geant4-environment-setup scripts scripts do not set the needed environment variables to support a non-system install of Qt. This means that QTHOME at minimum should be set, and possibly QTMOC, QTFLAGS and QTLIBPATH as well. This information can probably be derived from the information extracted by FindQt4.cmake.
To be reviewed in light of deprecation of GNUmake towards version X
Removed for next release due to deprecation of GNUmake for application.
