I'm not terribly familiar with using VTK outside of CMake, but I think
what you have is correct for qmake.

The issue is that vtkRenderingFreeType provides an object-factory
override for the vtkTextRenderer class, but it's not getting
registered with the object factory at runtime. I believe this is what
the VTK_MODULE_INIT macros do (someone correct me if I'm wrong).

I think adding a VTK_MODULE_INIT(...) for each of the linked VTK
libraries should fix this.

HTH,
