I asked about this a while ago [1] and got a response off-list that we
don't want to expose the base-system zstd because that could conflict
with pkgsrc zstd, especially if pkgsrc has a newer version.

One suggestion was to put the zstd shared library in /usr/lib/private
where the ssh library is.  Any program wanting to use zstd can then
.include "${NETBSDSRCDIR}/external/bsd/zstd/Makefile.zstd" .

That shouldn't be too hard, but I never got around to looking any
further at this.  If Someone(tm) gets this bit done, I've got patches
for zcat/gzip and libarchive to use zstd ready.  pkg_install then
gets zstd support for "free" via libarchive.

Cheers,
Simon.
