I just came across this as I was searching for something else, and it
looks like it was never answered. Sorry I missed the post, the
VTK_USE_FILE dependency is not required, but you must take care of
some things yourself including adding the compiler definitions
required for the object factory registration.

I am writing up some documentation for the VTK wiki which will answer
this in more detail. This is a work in progress, feedback/edits are
welcome.

Hopefully this will help people who follow, and my apologies for
missing this post.
