Sorry for the noise. Just adding
-DModule_vtkRenderingFreeTypeFontConfig=ON to my build and
libfontconfig1-dev to the build dependencies, and I get

    --  * vtkRenderingFreeTypeFontConfig, requested by
Module_vtkRenderingFreeTypeFontConfig.

in the VTK CMake output. Building now and will report back how it went.

Still interested in if vtkTextProperty::SetFontFamilyAsString(..) is
the right API to set the fontconfig family name.
