Actually, this doesn't help with the licensing incompatibility, given
that Inkscape already depends on the GPL v3+ GNU Scientific Library
(GSL) and that the bundled lib2geom sources within Inkscape make use of
GSL.  I've pointed that here:
https://gitlab.com/inkscape/inkscape/-/issues/784#note_343667232.

I've brought this to their attention, thank you.

That's a good idea.
