What is "os" in the above? If it's the environment variable OS then,
indeed, there's no equivalent on macOS (either kind of silicon).

I don't know whether Windows defines "OS", but if it does you could just
set Darwin (or whatever) as the default?

OS := external ("OS", "Darwin");

If you're using Alire, the generated config/{crate}_config.gpr contains
on macOS

Alire_Host_OS := "macos";

Excellent suggestion. The following worked:

package Linker is
case audio_config.Alire_Host_OS is
when "macos" =>
for Switches("Ada") use ("-L/opt/homebrew/lib/", "-lsndfile");
when others =>
for Switches("Ada") use ("-lsndfile");
end case;
end Linker;
