Thank you for your feedback.

I found this on zstd code that also help a lot:
On older versions of libzstd, this option does not exist, and
trying to set it will fail. Similarly for newer versions if they
are compiled without threading support

So I will check (not sure yet how ) if zstd packaged in ubuntu Jammy is
compiled with threading support.

Thank you again for your help and time.
Didier
