Bug: Unable to build on Alpine Linux due to dependency on execinfo.h

[acon96]

What happened?

Attempting to build the library on Alpine Linux based systems (musl instead of glibc) fails due to the dependency on execinfo.h which is NOT implemented by musl.

This dependency should be properly detected in the CMake build scripts and the functionality should be disabled on Linux systems that do not support the backtrace functionality.

Name and Version

Dependency was re-introduced in 2b1f616 for all Linux builds.

What operating system are you seeing the problem on?

Linux
