[vtkusers] Build VTK for Windows XP 32bit on Window 7 64bit machine

[Bryn Lloyd]

Hi Gib

Thanks for the suggestion. I have tried to analyze the problem with 
Dependency Walker and Process Monitor.

I also tried the cmake module CMakeVerifyManifest.cmake, which suggests 
there might be conflicts with the runtime dependencies. Our application 
points to two different runtime libraries 9.0.2x and 9.0.3x (from third 
party libraries that we use, like enthought python). The computer has a 
newer version installed 9.0.6x, but not the exact same version. I don't 
know if this might be the issue.

It seems that VTK does not embed the CRT dependency (manifest) in the 
dll. Not sure if this might be needed or if there is an option in cmake 
to add it. Maybe this is "Manifest Hell"  ;-(

There might also be other runtime dependencies, e.g. for MFC or OpenMP. 
Does VTK use OpenMP? But a quick search suggests it doesn't use OpenMP. 
Also, I compiled VTK without MFC support, but our application does use MFC.
