Hi Rafael,
Quick update:
I just checked: Cygwin does not seem to have updates for these two packages. I
will have to look at some other platforms.
Regards,
Arjen

It works for me with these versions:
- SWIG 4.1.0
- Octave 7.3.0
Could you please test with them?

The ideal situation would be to allow users to enable both static and dynamic,
if they wish so. Is this what you are intending to do?
