[Insight-users] ITK 4.2 - GPUMeanImageFilter - itkGPUKernelManager

[Yass Jd]

Dear Kris,

Thank you for your answer !

Here is my CMakeLists:

    cmake_minimum_required (VERSION 2.8.5)
    project (fMRI)

    #set (CMAKE_VERBOSE_MAKEFILE ON)
    set(CMAKE_CXX_FLAGS "-g -Wall")

    if(COMMAND cmake_policy)
       cmake_policy(SET CMP0003 NEW)
    endif(COMMAND cmake_policy)

    # Find ITK.
    FIND_PACKAGE(ITK REQUIRED)
    IF(ITK_FOUND)
       INCLUDE(${ITK_USE_FILE})
    ENDIF(ITK_FOUND)

    add_executable(ReadDCMWriteNii niftihandler.cpp main.cxx )
    target_link_libraries(ReadDCMWriteNii  ${ITK_LIBRARIES})

Should be OK right ? Seems like I'm not linking well something...

Best regards,
Yass Jd.
