I'm having a lot of trouble wrapping my head around what you're trying
to do here.

If you're packaging openssh, in the openssh.spec file, you'd want to have:

BuildRequires: openssl >= 0.9.7f

When the openssh SRPM is built, it will link to openssl, and a shared
library dependency will be added to the resulting openssh binary rpms.

If this openssh SRPM generates three binary RPMs (openssh,
openssh-server, openssh-client), you can add explicit Requires to
openssh for openssh-server and openssh-client. This will ensure that yum
install openssh pulls all three packages in to resolve dependencies. If
you want the daemon/service to start immediately after install, you can
enable and start the systemd (or old sysvinit) service in %post, as
documented here:

https://fedoraproject.org/wiki/Packaging:ScriptletSnippets#Systemd

You should never ever be building code in %post (it should happen in the
%build section). You should never ever be calling rpm or yum within the
spec file.
