[vtkusers] compiling VTK against CUDA 4.2

[Cook, Rich]

Hello
I'm new to the list and apologize if this is obvious or seen before.  I Googled around a bit for the answer but cannot find it.  

My question seemed simple before I tried it.  How does one compile VTK in order to use CUDA? A user of mine requested this;  I'm not a VTK expert and am not sure specifically what she plans to do with the result.  

I see CUDA stuff like this in the source, making me think this should be possible and the question at least makes sense to ask: 

../VTK/Graphics/vtkYoungsMaterialInterface.cxx:77204:#ifdef __CUDACC__

So, I tried a naive approach: 

export CC=nvcc
export CXX=nvcc
export CPP=nvcc

mkdir vtk-build
cd vtk-build
cmake ../VTK

cmake fails as follows, making me think maybe I have to build CMake with nvcc as well?  That would be a bit ugly, but I just want to make sure I'm going down the right path. 
Any help is greatly appreciated.
