Can't compile xxh3, Erlang/OTP 26

[benartuso]

error: could not compile xxh3 (lib) due to 2 previous errors

===> Uncaught error in rebar_core. Run with DIAGNOSTIC=1 to see stacktrace or consult rebar3.crashdump
===> When submitting a bug report, please include the output of rebar3 report "your command"

** (Mix) Could not compile dependency :xxh3, "/Users/ben/.mix/elixir/1-16/rebar3 bare compile --paths /Users/ben/oxen/OxenHub/_build/dev/lib/*/ebin" command failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile xxh3 --force", update it with "mix deps.update xxh3" or clean it with "mix deps.clean xxh3"

Looks possibly related to #2, let me know if there's any other output that's useful!

Which versions of rust, erlang, and elixir do you use?

I'm also getting a:

It does work with iex -S mix though.

By hard coding the right value to __PATH I was able to make it work:

-define(load_nif_from_crate(__CRATE, __INIT),
    (fun() ->
        __APP = ?CARGO_LOAD_APP,
        __PATH = "/home/myuser/myproj/deps/xxh3/priv/crates/xxh3/xxh3",
        erlang:load_nif(__PATH, __INIT)
    end)()
).

You might want to fix how that path discovery works.
