I have packaged `wolfssl` and placed at For CentOS 9 - https://rpm.kamailio.org/centos/9/master/master/x86_64/Packages/w/ For CentOS 8 - https://rpm.kamailio.org/centos/8/master/master/x86_64/Packages/w/
If you need another dist, then you rebuild `.src.rpm`.
Could you install packaged wolfssl and update Makefile to use param to allow the use of shared library linking?
As example, you can find [in spec file](https://github.com/kamailio/kamailio/blob/55b3ce67709e56be116bb7077931ba7f4c...) [in Makefile](https://github.com/kamailio/kamailio/blob/master/src/Makefile.radius#L24)
