Below is the cxx file and the CMakeLists.txt

 #include "itkImage.h"
#include "itkImageFileReader.h"

int main(int argc, char *argv[])
{
  if(argc < 2)
    {
    std::cerr << "Required: filename" << std::endl;

    return EXIT_FAILURE;
    }
  std::string inputFilename = argv[1];

  typedef itk::Image< unsigned char, 2 >  ImageType;

  typedef itk::ImageFileReader<ImageType> ReaderType;
  ReaderType::Pointer reader = ReaderType::New();
  reader->SetFileName(inputFilename.c_str());
  reader->Update();

  return EXIT_SUCCESS;
}


cmake_minimum_required(VERSION 2.6)

PROJECT(ImageFileReader)

FIND_PACKAGE(ITK REQUIRED)
INCLUDE(${ITK_USE_FILE})

ADD_EXECUTABLE(ImageFileReader ImageFileReader.cxx)
TARGET_LINK_LIBRARIES(ImageFileReader ${ITK_LIBRARIES})


What do you mean by

"If your testing code uses the test driver and specifies "ITK-TestKernel" in
your module dependency list, it should run smoothly."

I built ITK with testing enabled with no change.
