The error appears at the configure stage. Maybe try and update your build tooling. cmake latest version is 3.29, you're using 3.26. But this is not a brotli issue. Also, I'm not even sure this project can be easily compiled on Mac OS (maybe, maybe not).

Because at the end of the day, it's very likely nginx will run on GNU/Linux, so maybe another approach for you would be to use Docker instead of your native tooling, which, to be honest, is not great on Mac.

Mac OS is a great operating system that allows you to open Safari and browse Apple.com to buy a newer mac. But IMHO it's not so great when you want to do things such as compiling a webserver encoding module in C.
