Hi James,

This is great !

Thanks for putting it together and sharing it.

I tested it with the CUDA-ITK directory that we have
in the NAMIC Sandbox at:

http://svn.na-mic.org/NAMICSandBox/trunk/CUDA-ITK/

where we used to have an older version of these files
in the subdirectory:

http://svn.na-mic.org/NAMICSandBox/trunk/CUDA-ITK/CMake/cuda/

--

Configuration with CMake went smoothly,

but when building, I got the warning messages below
(at the end of this email).

It would seem that some of the ITK C++ compilation
flags are passed to the cuda compiler, and get rejected.

Does that ring any bell ?

  Thanks

     Luis
