Where, of course, $QTDIR is really the directory where the Qt 4.5.0 libs are.
Alternatively, if you have /installdir/bin and /installdir/lib, then apps in
/installdir/bin could be linked with -R $ORIGIN/../lib. This time, $ORIGIN is a
literal string, not an environment variable. Then copy your Qt libs to
/installdir/lib, and no more conflicts or need for LD_LIBRARY_PATH.
