for linux I use something like the following in my gpr file:

case os is

    when "GNU/Linux" =>

not sure what is equivalent for the M1 Mac?

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;
