You could also do this, QT_USE_FILE aka UseQt4.cmake will include all your Qt 
libraries and setup the QT_LIBRARIES variable so that it will contain all your 
Qt libs.  It doesn't save a ton of space when you are using one Qt library, but 
it pays off when you start using more.

SET ( QT_USE_OPENGL TRUE )
INCLUDE ( ${QT_USE_FILE} )

INCLUDE_DIRECTORIES (
	${CMAKE_CURRENT_BINARY_DIR}
	)

TARGET_LINK_LIBRARIES ( mdi
	${QT_LIBRARIES}
	${QGLVIEWER_LIBRARY}
	)
