[CMake] C# support

[Mathieu Malaterre]

'lo,

  I have added a bug report for C# support in CMake.

  http://vtk.org/Bug/view.php?id=7918

This will serve mostly to see what is the interest in the community. I
have added the link to the minimal cmake-modules I wrote:

  Feel free to add any other info / 3rd party work I missed.

Thanks,
