#
# function QT4_USE_MODULES( target [link_type] modules...)
# Make <target> use the <modules> from Qt. Using a Qt module means
# to link to the library, add the relevant include directories for the module,
# and add the relevant compiler defines for using the module.
# Modules are roughly equivalent to components of Qt4, so usage would be
# something like:
# qt4_use_modules(myexe Core Gui Declarative)
# to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument can
# be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the same argument
# to the target_link_libraries call.
#
#
# Below is a detailed list of variables that FindQt4.cmake sets.
# QT_FOUND If false, don't try to use Qt.
