# - Find QT 4
# This module can be used to find Qt4.
# This module defines a number of key variables and macros. First is 
# QT_USE_FILE which is the path to a CMake file that can be included to compile
# Qt 4 applications and libraries.  By default, the QtCore and QtGui 
# libraries are loaded. This behavior can be changed by setting one or more 
# of the following variables to true:
#                    QT_DONT_USE_QTCORE
#                    QT_DONT_USE_QTGUI
#                    QT_USE_QT3SUPPORT
#                    QT_USE_QTASSISTANT
#                    QT_USE_QTDESIGNER
#                    QT_USE_QTMOTIF

#                    QT_USE_QTXML
# All the libraries required are stored in a variable called QT_LIBRARIES.  
# Add this variable to your TARGET_LINK_LIBRARIES.
