Doesn't work:

git checkout main
rm -rf _build deps
mix deps.get
mix deps.compile

This works, but why not the above..

git checkout main
rm -rf _build deps
mix deps.get
mix deps.compile elixir_make
mix deps.compile
iex -S mix

ElixirHidrawErrorNix.enumerate

Works using nix, while commenting out hidraw:

git checkout nix-build-working-without-hidraw
rm -rf _build deps
mix deps.get
mix deps.compile
mix deps.nix
mix deps.compile
nix build --print-build-logs
