# This module defines
# QT_USE_FILE                   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
