[vtkusers] Linking to VTK static libraries on Windows

[Gib Bogle]

I've shifted to a simpler example.  I have a very basic Qt/VTK test program 
(QVTK_test) which works when linked to VTK shared libraries.  It uses QVTKWidget 
and vtkRenderWindowInteractor to render a cylinder.  As such it is very similar 
to the VTK Cylinder example - it also uses ctkCylinderSource.
VTK-src\build\examples\all\rendering
The Cylinder example builds correctly with static VTK libraries, with no 
warnings.  My QVTL_test build gives this output (some warnings and one error):

I'm focussing on this because the vtkCylinderSource link error also occurs when 
I build the application that I originally posted about.  This current example 
looks more tractable because there is only this single error.

I've looked carefully at the Project Properties for the Cylinder build, and I've 
made sure that the QVTK_test Properties are the same, or as close as possible 
(my program uses Qt, so there are additional libraries and include directories). 
  I am using exactly the same libraries, in the same order (except for the extra 
Qt libraries).  All to no avail - I still get the unresolved external symbol 
error for vtkCylinderSource::New(void).

I've been ignoring the warnings, because I don't understand them.  Maybe they 
are significant.
