We obviously can't do as much for you when you don't use CMake, and
many Qt projects use CMake as their build system. If you want to
initialize modules yourself you would need to add the compiler
definitions CMake takes care of adding, and ensuring you link to the
correct implementation modules.

Look at the bottom of the wiki page I linked to
(http://www.vtk.org/Wiki/VTK/Build_System_Migration#How_Implementation_Modules_Are_Initialized)
and you can see an example of how we initialize vtkRenderingOpenGL for
the vtkRenderingCore module, the number refers to the number of
modules to enable for that module (1, 2, 3, 4, ...).
