[Insight-users] QtITK linking problems

[Rudi Ratlos]

Hi Luis,
thanks for your help. I am using CMake 2.0.2 and the
following CMakeLists.txt:

PROJECT(QtITKExample)


################################################### 
# Find ITK
#
INCLUDE (${CMAKE_ROOT}/Modules/FindITK.cmake)
IF (USE_ITK_FILE)
INCLUDE(${USE_ITK_FILE})
ENDIF(USE_ITK_FILE)
# 
# Find QT
#
INCLUDE (${CMAKE_ROOT}/Modules/FindQt.cmake)
INCLUDE_DIRECTORIES(
${QT_INCLUDE_DIR}
${QT_INCLUDE_PATH}
)
LINK_LIBRARIES (
   ITKCommon
   ITKBasicFilters
   ITKAlgorithms
   ITKIO
   itkpng
   itkzlib
   ${QT_QT_LIBRARY}
 )
IF(WIN32)
ADD_DEFINITIONS(-DQT_DLL) 
ENDIF(WIN32)

SET(QtITK_SRCS
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_SRCS)

#####################################################

and I am getting following errors:
