Undefine Symbols vtkImageViewer2::New(), QT-VTK Mac OSX 10.6.8

I'm using VTK to read a DICOM series. I can compile (using CMake) VTK example code and it runs well. Now, I'm trying to use Qtcreator and Qt4.8.5 to create a GUI. I have linked the library and include path on project.pro.

When I build, I get:

Undefined symbols:
  "vtkImageViewer2::New()", referenced from:
     vtkSmartPointer<vtkImageViewer2>::New()        in mainwindow.o
ld: symbol(s) not found

I checked, the Include path, and it includes /usr/local/vtk-6.1/include/vtk-6.1/ which contains vtkImageViewer2.h.

What's wrong with my project?

As an addendum to David's answer, do not forgot to add ${VTK_LIBRARIES} (defined by the VTK Use file) to your library or binary/executable:

TARGET_LINK_LIBRARIES(myLib ${VTK_LIBRARIES})

and the paths to the libraries as:

link_directories(${VTK_LIBRARY_DIRS})

That is a linker error, so your project is indeed finding vtkImageViewer2.h correctly. You should use CMake to create your project, then you can simply do

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

and all of the VTK linking will be taken care of for you.
