[vtkusers] no matching function for call to vtkPolyData::GetNumberofPoints()

[Mathieu Malaterre]

Because vtkPolyDataReader is in vtkIO, so you should link against this 
lib. If you are not sure about which lib to use link against vtkHybrid 
(contains link to all other vtk lib)

e.g:
ADD_EXECUTABLE(reader reader.cxx )
TARGET_LINK_LIBRARIES (reader
   vtkHybrid
)



BTW you do 'return 0' on a return void function
