[vtkusers] Using VTK with CMake: link errors

[Nicholas Kinar]

Hello,

I had originally posted this question to the vtkusers mailing list.  
However, after receiving feedback from other VTK users it is also 
apparent that there is a possibility my question belongs on the cmake 
mailing list.

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 (binary version from website)
i686-apple-darwin10-gcc-4.2.1
llvm version 2.6svn,  Apple Build #2207-05
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 tried the most recent release version of CMake pulled from git and 
the binary (pre-packaged) version on the Kitware website.  Both generate 
makefiles with the same error on Mac OS X.

I've written a CMakeLists.txt file to generate the makefile.  This 
CMakeLists.txt file works well on GNU/Linux (Ubuntu x86_64, 
2.6.32-24-generic kernel) with gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 and GNU 
ld (GNU Binutils for Ubuntu) 2.20.1-system.20100303.  On GNU/Linux, the 
CMakeLists.txt file generates a makefile that successfully builds my 
program and links it with the VTK library.

Here is the CMakeLists.txt file:

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

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 the makefile generated by cmake builds without problems on 
Ubuntu GNU/Linux, a similarly-generated makefile produces the following 
errors on Mac OS X.  It appears that CMake is finding the VTK library in 
the Python.framework directory in lieu of the one installed into 
/usr/local/lib.  Here are the errors produced on Mac OS X:

What am I doing wrong here, and what should I change to ensure that 
CMake locates the proper version of VTK on Mac OS X?
