[vtkusers] Odd Qt-ITK-VTK situation

[Gib Bogle]

You are right!  I don't know why I selected that option (or didn't deselect it).  In fact I don't even know what it's for.  Is it necessary if you ever want to use VTK with ITK?

Thanks
Gib

Gib,

Are you sure you didn't build ITK on the system that is behaving oddly
with the VTK "glue" module enabled? That's the only thing I can think
of that might explain the linker's complaint.

Thanks,
Cory
