AFAIK, this library is not built if the TK_LIBRARY is not defined.
Look in Rendering/CMakeLists.txt::

IF (VTK_WRAP_PYTHON)
  IF (TK_LIBRARY)
     IF(NOT VTK_USE_COCOA)
       SET(RenderingPythonTkWidgets_SRCS
          vtkTkWidgetsInit.cxx
          vtkTkRenderWidgetPython.cxx
          vtkTkImageViewerWidgetPython.cxx
          )
[...]

So, I think if you turn on VTK_WRAP_PYTHON but don't set the
TK_LIBRARY this should never be built.

Could you test this and see?
