Hi,

I have the previous working fine code when I used VTK 5.6.1+ITK 3.20.1, but
I got lots of problem when I wanted to reuse the code while upgrading to
the new VTK/ITK version.

My environment, Ubuntu 12.04, CMake 2.8.12.2, VTK 6.1, ITK 4.7. ItkVtkGlue
is turned ON.

The CMakeLists.txt is as the following, I checked the example,

cmake_minimum_required(VERSION 2.8)

PROJECT(BackProjection)

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

if (ITKVtkGlue_LOADED)
  find_package(VTK REQUIRED)
  include(${VTK_USE_FILE})
else()
  find_package(ItkVtkGlue REQUIRED)
  include(${ItkVtkGlue_USE_FILE})
  set(Glue ItkVtkGlue)
endif()
add_executable(ReadPLY MACOSX_BUNDLE ReadPLY.cxx)
target_link_libraries(ReadPLY ${Glue} ${VTK_LIBRARIES} ${ITK_LIBRARIES})

###

When I build with make, the error is,

[100%] Building CXX object CMakeFiles/ReadPLY.dir/ReadPLY.cxx.o
Linking CXX executable ReadPLY
CMakeFiles/ReadPLY.dir/ReadPLY.cxx.o: In function
`vtkSmartPointer<vtkPLYReader>::New()':
ReadPLY.cxx:(.text._ZN15vtkSmartPointerI12vtkPLYReaderE3NewEv[_ZN15vtkSmartPointerI12vtkPLYReaderE3NewEv]+0xd):
undefined reference to `vtkPLYReader::New()'
collect2: error: ld returned 1 exit status
make[2]: *** [ReadPLY] Error 1
make[1]: *** [CMakeFiles/ReadPLY.dir/all] Error 2
make: *** [all] Error 2

Interestingly, when I fully remove anything about ITK in my CMakeLists.txt,
it doesn't show any error. So I suspect it is the ITK's build macro which
is breaking my VTK code compiling.
The working CMakeLists.txt is like,

cmake_minimum_required(VERSION 2.8)

PROJECT(ReadPLY)

find_package(VTK REQUIRED)
include(${VTK_USE_FILE})

add_executable(ReadPLY MACOSX_BUNDLE ReadPLY.cxx)

if(VTK_LIBRARIES)
  target_link_libraries(ReadPLY ${VTK_LIBRARIES})
else()
  target_link_libraries(ReadPLY vtkHybrid vtkWidgets)
endif()

And the ReadPLY.cxx source code is, it is actually a VTK example, doesn't
contain any ITK code. But I have the other source code file has ITK code,
presenting this example just to show the problem.

#include <vtkPolyData.h>
#include <vtkPLYReader.h>
#include <vtkSmartPointer.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>

int main ( int argc, char *argv[] )
{
  if(argc != 2)
    {
    std::cout << "Usage: " << argv[0] << "  Filename(.ply)" << std::endl;
    return EXIT_FAILURE;
    }

  std::string inputFilename = argv[1];

  vtkSmartPointer<vtkPLYReader> reader =
    vtkSmartPointer<vtkPLYReader>::New();
  reader->SetFileName ( inputFilename.c_str() );

  // Visualize
  vtkSmartPointer<vtkPolyDataMapper> mapper =
    vtkSmartPointer<vtkPolyDataMapper>::New();
  mapper->SetInputConnection(reader->GetOutputPort());

  vtkSmartPointer<vtkActor> actor =
    vtkSmartPointer<vtkActor>::New();
  actor->SetMapper(mapper);

  vtkSmartPointer<vtkRenderer> renderer =
    vtkSmartPointer<vtkRenderer>::New();
  vtkSmartPointer<vtkRenderWindow> renderWindow =
    vtkSmartPointer<vtkRenderWindow>::New();
  renderWindow->AddRenderer(renderer);
  vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
  renderWindowInteractor->SetRenderWindow(renderWindow);

  renderer->AddActor(actor);
  renderer->SetBackground(0.1804,0.5451,0.3412); // Sea green

  renderWindow->Render();
  renderWindowInteractor->Start();

  return EXIT_SUCCESS;
}
