[vtkusers] vtk6 porting question (segfault)

[Bill Lorensen]

The built examples will be in the bin directory of your VTK.

A more extensive set of examples are on the Wiki:
http://vtk.org/Wiki/VTK/Examples/Cxx

each has a valid CMakeLists.txt file.

You can also build them all by following these instructions:
