I use qt4 with itk, and it works. below is my cmakelists, maybe it will 
help. (i also had problems getting it to work. try googling the 
insight-users mailing list history)

PROJECT(Test)

FIND_PACKAGE(ITK)
IF(ITK_FOUND)
  INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
    MESSAGE(FATAL_ERROR "ITK NOT FOUND --C")
ENDIF(ITK_FOUND)

FIND_PACKAGE(Qt)
IF(QT_USE_FILE)
  SET(QT_USE_QT3SUPPORT TRUE)
  INCLUDE(${QT_USE_FILE})
ELSE(QT_USE_FILE)
  SET(QT_LIBRARIES   ${QT_QT_LIBRARY})
ENDIF(QT_USE_FILE)


INCLUDE_DIRECTORIES( ${QT_INCLUDE_DIR} )
INCLUDE_DIRECTORIES( ${CMAKE_CURRENT_BINARY_DIR} )

LINK_LIBRARIES(${QT_LIBRARIES})

#make an executable from the cpp-files in QT_SRCS
SET(QT_SRCS

SET(QT_HDRS
	header-files..
)

#header that needs "moc-ing"
SET(cqtlib_MOC_HDRS

QT4_WRAP_CPP(cqtlib_MOC_SRC ${cqtlib_MOC_HDRS})

SET(cqtlib_SRCS

	PLogic.cpp
)

ADD_LIBRARY(Segmentation SHARED ${cqtlib_SRCS} ${cqtlib_MOC_HDRS})
