# searches for the installed versions of QT
# This should only be used if your project can work with both qt3 and gt4.
# If not, you should just directly use FindQt4 or FindQt3.
#
# Sets QT3_INSTALLED to TRUE if qt3 is installed
# Sets QT4_INSTALLED to TRUE if qt4 is installed
# So, if you had a project that worked with Qt3 and Qt4, but preferred Qt3, you would do this:
# INCLUDE(CMakeQtInstalled)
# IF(Qt3_INSTALLED)
# INCLUDE(FindQt3)
# ELSEIF(Qt3_INSTALLED)
# IF(Qt4_INSTALLED)
# INCLUDE(FindQt4)
# ENDIF(Qt4_INSTALLED)
