I don't know which version of the code you're using. Does it have the

vtkTypeMacro(vtkPointSetNormalEstimation, vtkPolyDataAlgorithm);

as it does here:

https://github.com/daviddoria/PointSetProcessing/blob/master/vtkPointSetNormalEstimation.h

A long time ago (probably at the time the VTK Journal version of the
code was written) this used to be a different macro and could
potentially cause this sort of error when using a recent VTK.

I would try building this:
https://github.com/daviddoria/PointSetProcessing

and let us know if you get the same error.
