json pointer : syslog-ng compilation error - makefile

Question

I want to install syslog-ng on SUSE Linux Enterprise Desktop 15 SP2 which is offline. I downloads file on github https://github.com/syslog-ng/syslog-ng/releases/tag/syslog-ng-3.35.1. Uploaded to my server. Uncompressed to run ./configure which worked, but when I tried make, I have this error.

I don't know which library is missing. Can you help me figuring out which library should I install?
