//proc/self/root/usr/share/cmake/Modules/FindQt.cmake

# - Searches for all installed versions of Qt.
# This should only be used if your project can work with multiple
# versions of Qt.  If not, you should just directly use FindQt4 or FindQt3.
# If multiple versions of Qt are found on the machine, then
# The user must set the option DESIRED_QT_VERSION to the version
# they want to use.  If only one version of qt is found on the machine,
# then the DESIRED_QT_VERSION is set to that version and the
# matching FindQt3 or FindQt4 module is included.
# Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module
# is included.
#
#  QT_REQUIRED if this is set to TRUE then if CMake can
#              not find Qt4 or Qt3 an error is raised
#              and a message is sent to the user.
#
#  DESIRED_QT_VERSION OPTION is created
#  QT4_INSTALLED is set to TRUE if qt4 is found.
#  QT3_INSTALLED is set to TRUE if qt3 is found.
