I documented this on the VTK 6 migration guide (build system) linked
from the main VTK wiki page,

http://vtk.org/Wiki/VTK/Build_System_Migration

The missing piece (that can be taken from option 3) is
set_property(DIRECTORY APPEND PROPERTY COMPILE_DEFINITIONS
${VTK_DEFINITIONS}) which will ensure that the object factories are
initialized. Unfortunately you were not very clear on "but it seems
not enough" so I am guessing this is the part that was not enough. You
must also depend on the relevant implementation modules at this time -
such as vtkRenderingOpenGL.

Hope that helps, including the use file makes things easier but you
really don't have to do that (we expose all the relevant variables and
you can inspect the CMake code in the use file if you wish to
replicate parts that are relevant in your project).
