The suggested method is to use a CMakeLists.txt file to generate a project.

Every example has an associated CMakeLists.txt file (for example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/SimplePointsReader

You just need to write
 target_link_libraries(YourProgram ${VTK_LIBRARIES})

and everything is taken care of for you.
