sqlcmd cannot find odbc 17 on MacOS Big Sur

ls -al of /usr/local/opt revealed that openssl was linked to openssl@3 instead of [email protected].

rm /usr/local/opt/openssl
ln -s /usr/local/Cellar/[email protected]/1.1.1l_1 /usr/local/opt/openssl

Resolved issue.

Warning: This will break any brew program you may have installed that relies on openssl 3. Wasn't an issue for me, but ymmv.
