Using the operating system provided websockets library

[rishithaminol]

I was able to compile with using OS provided websockets library.

OS: Fedora 39

What we have to do is install websockets (dnf install libwebsockets-devel) and do few modification to the Cmake build mechanism. Then it will pick up the OS provided libwebsockets library.

Any thoughts?

Apology. This already there I think.

Thanks for your advice. This is what I've been planning to do since Ubuntu 22.04 LTS was released (the libwebsockets-dev package is compatible with the c client library from then).
