Thank you.

AFAICS this happens because of the fiddling with the source and binary paths in SWIG_ADD_SOURCE_TO_MODULE. I don't understand what is happening there and why it doesn't just use get_filename_component(ABSOLUTE).

As a workaround you could put the source file as a relative path to your source dir into the CMakeLists.txt, that should work for the moment.
