[vtkusers] undefined reference

[Marc Ruiz Altisent]

Hi Aida,

VTK changed to a modular system some time ago and the library names
changed. You just need to find the new ones. The names match the directory
containg the classes: for example vtkPolyDataToImageStencil is in
Imaging/Stencil and the library is vtkImagingStencil, with a suffix of the
VTK version, e.g. vtkImagingStencil-8.1. Similarly, for vtkImageAccumulate
you need vtkImagingStatistics (+ suffix).
