[vtkusers] Using VTK with CMake: link errors

[Nicholas Kinar]

Hello,

I'm writing a program for a research application, and I would like to 
use Cmake as the makefile generation tool.  Here is the basic 
information pertaining to my development platform:

cmake version 2.8.2
i686-apple-darwin10-gcc-4.2.1
Snow Leopard 10.6.4 on an x86_64 Macbook Pro
vtk-5.6.0 (stable version)

The VTK libraries have been installed into the /usr/local directory.

I've written a CMakeLists.txt file to generate the makefile.  Here is 
the file:

cmake_minimum_required (VERSION 2.6)
project (fdtd-cuda-1)
find_package(VTK REQUIRED)
include_directories( ${VTK_INCLUDE_DIRS} )
include_directories(/Volumes/FILES/CODE-LIBRARY/utilities)
include_directories(/Volumes/FILES/Programs/common/TNT)
include_directories(/Volumes/FILES/Programs/common/boost/boost_1_43_0)
include (${VTK_USE_FILE})
add_executable (fdtd-cuda-1 main.cpp)
target_link_libraries(fdtd-cuda-1 ${VTK_LIBS})

Within the main.cpp file, of my C++ program I am using the following VTK 
headers:

#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkInteractorStyleImage.h>
#include <vtkRenderer.h>
#include <vtkJPEGReader.h>
#include <vtkImageActor.h>
#include <vtkCommand.h>
#include <vtkCallbackCommand.h>
#include <vtkSmartPointer.h>

Although CMake generates the UNIX makefile properly, it appears that the 
linker cannot find some symbols:

Linking CXX executable fdtd-cuda-1

What is happening here, and what should I change in my CmakeLists.txt 
file to be able to properly compile this program?  It appears that there 
is a problem with the linker being unable to find some libraries.
