[vtkusers] vtkPowerCrustSurfaceReconstruction unresolved external symbol

[Bayliss, Chris (Chicago)]

Do I add that line to the cmakelists file in the hybrid directory?  I apologize for any silly questions I may ask, I am very new to cmake, vtk, C++, and writing software in general.

Thanks,

Chris
