[vtkusers] vtkPolyDataMapper "error LNK2001: unresolved external symbol".

[Dave Partyka]

When your program is executed it is trying to find the vtk dlls but cannot
find them. One thing you can do is add your vtk\bin\debug directory to your
PATH. You can also do this from within visual studio by going under
Properties to your project and then go to Debugging. On that tab there is
the Environment setting that you could set something like
PATH=PATH;c:\vtk\bin\debug for example.
Hope that helps.
