right, i figured it out, after i saw it. thanks for the lengthy explanation.
Speaking with Anssi about this, he mentions that
%{mklibname mysql %{major}} = %{version}-%{release}
would have also solved the issue.

</I>><i> As mariadb is a binary replacement for mysql, why not just named the

</I>
i understand, however the %mklibname macro is actually meant for this, and
will not change.
furthermore, speaking with Anssi about this,
><i> Personally, I don't think libmysqld18 (now it is named
</I>><i> libmariadb-embedded18) should have any relationship with libmysqld0.

</I>
in respect to the embedded libraries, it's not actually,
their upstream version was more or less copied from mysql and the developer
who implemented the cmake change in 5.5 branch for mysql, is the same person
who's now maintaining that 5.5 cmake branch.
I mentioned that this library should be versioned, and that it's not at this
time, he agreed, and said that since it's ABI compatible with mysqlclient,
that he should not use 0 major, but the 18 major (same as mysqlclient)
the code is still 100% exactly the same, it just went from unversioned in
upstream to versioned.
since we had versioned manually mysqld to major 0, i provided the
compatibility symlinks for it.
