[vtkusers] need help in using vtkPolyDataReader

[Martin Dunschen]

Where is vtkIO.lib? Make sure it is in your library serch path. You set 
the lib search path either from project settings just form this 
project, or from tools->options, I think the directories tab.

Then you also need to copy the DLL into the same directory as the 
executable... can be done as a post build step, in project settings

look further up, another user had a similar problem
