Description Vitaly Dyackhov 2023-09-26 01:54:10 PDT 
Since we enable `-fvisibility=hidden` and `-fvisibility-hidden-inlines`, `backtrace()` cannot resolver pointer address to function names.
We can use `libbacktrace`[1] to symbolize addresses and generate meaningful backtraces.

So, I don't think libbacktrace actually installs a pkg-config file, so I'm thinking the `pkg_check_modules()` call here is guaranteed to fail. Am I wrong? I think it should be removed.

I also notice this library has never released before ever. I am having second thoughts about depending on it by default. Maybe we should turn this OFF by default. I'm wondering if Ian has any plans to ever release it.
