   1 # - Find QT 4
   2 # This module can be used to find Qt4.
   3 # The most important issue is that the Qt4 qmake is available via the system path.
   4 # This qmake is then used to detect basically everything else.
   5 # This module defines a number of key variables and macros. First is
   6 # QT_USE_FILE which is the path to a CMake file that can be included to compile
   7 # Qt 4 applications and libraries.  By default, the QtCore and QtGui
   8 # libraries are loaded. This behavior can be changed by setting one or more
   9 # of the following variables to true:
  10 #                    QT_DONT_USE_QTCORE
  11 #                    QT_DONT_USE_QTGUI
  12 #                    QT_USE_QT3SUPPORT
  13 #                    QT_USE_QTASSISTANT
  14 #                    QT_USE_QTDESIGNER
  15 #                    QT_USE_QTMOTIF
  16 #                    QT_USE_QTMAIN
  17 #                    QT_USE_QTNETWORK
  18 #                    QT_USE_QTNSPLUGIN
  19 #                    QT_USE_QTOPENGL
  20 #                    QT_USE_QTSQL
  21 #                    QT_USE_QTXML
  22 #                    QT_USE_QTSVG
  23 #                    QT_USE_QTTEST
  24 #                    QT_USE_QTUITOOLS
  25 #
  26 # All the libraries required are stored in a variable called QT_LIBRARIES.
