[vtkusers] VTK 6.1 linking/autoinit

[Marcus D. Hanwell]

This is now in master, I will find a little time to update
documentation on the wiki. I think this approach will be simpler in
circumstances where you know exactly which modules you want
initialized and cannot simply use compiler definitions. Please let me
know if you hit any problems - in local tests this performed as
expected.

I take it this looks like a good option for you? I posted the link to give you and others a chance to comment.

I have asked Brad to check over the macro code, you could effectively copy the snippet into your project (adjusting the macro name to avoid conflicts once this is merged) if you want to use it with older versions of VTK too. It is the simplified version of what autoinit does when you don't want the build system to take care of everything for you (the original goal of autoinit).
