If I wanted to find the package maintainer, I would first find which package the library belongs to.
For instance, if you are already on OpenSUSE, the place to start is with the library file itself, e.g.,
rpm -qf library-filename that is, library-filename is the actual name of the file you are interested in. That rpm command identifies the name of the package.
Once you have the package name, then you can search in the appropriate place for it.
By the way, your search link produced these results:
but using the actual package name, you might have seen this:
After having found the appropriate package, you might find the maintainer information in the source's ".spec" file. rpmfind.net or rpmbone.net seem to usually have links for this, e.g.,
libcryptopp-devel-5.6.2-7.4.1 RPM for aarch64
