Hi Matt,
 I changed CMakeLists.txt as you suggested as follows:


PROJECT(myProject)

FIND_PACKAGE ( ITK)

IF ( ITK_FOUND)

INCLUDE( ${USE_ITK_FILE} )

ENDIF( ITK_FOUND)

 # Find QT

FIND_PACKAGE( Qt4 REQUIRED )

#INCLUDE( ${QT_USE_FILE} )

INCLUDE_DIRECTORIES(

${QT_INCLUDES}

${QT_INCLUDE_DIR}

${QT_QTGUI_INCLUDE_DIR}

${QT_QTCORE_INCLUDE_DIR}

${CMAKE_CURRENT_BINARY_DIR}

${CMAKE_CURRENT_SOURCE_DIR}

)

 SET( QtITK.cpp itkQtProgressBar.cxx qtITK.cxx)

SET( QtITK_MOC_SRCS itkQtAdaptor.h itkQtLightIndicator.h)

#IF(QT_WRAP_CPP)

# QT_WRAP_CPP(QtITK QtITK_SRCS QtITK_MOC_SRCS)

#ENDIF(QT_WRAP_CPP

ADD_EXECUTABLE( QtITK QtITK.cxx)

TARGET_LINK_LIBRARIES (QtITK

${ITK_LIBRARIES}

${QT_LIBRARIES}

${QT_QTCORE_LIBRARY}

${QT_QTGUI_LIBRARY}

)





But I still got the same linking error? any other suggestions?

Thanks,

Adem.
