Re: Compile 12.2 with specific OpenSSL libraries

Thanks, Tom. I really appreciate you taking the time to help me out!

I think I'm good now. I ran `readelf -d libpq.so | grep runpath` and I see
that the path I specified in --with-libraries is present (albeit after my
system path). It also appears the version I expected of libssl is being
used (libssl.so.1.1).

At this point I think it's fairly straightforward to set the rpath to lock
down the runtime linking as you mentioned. Thanks again!
