# Elixir dependencies are fetched and compiled as part of the alias

# mix(1) startup time is quite high. Thus we prefer to run it once, even
# though it kind of breaks the Erlang.mk model.
#
# We write `y` on mix stdin because it asks approval to install Hex if
# it's missing. Another way to do it is to use `mix local.hex` but it
# can't be integrated in an alias and doing it from the Makefile isn't
# practical.
#
# We also verify if the CLI is built from the RabbitMQ source archive
# (by checking if the Hex registry/cache is present). If it is, we use
# another alias. This alias does exactly the same thing as `make_all`,
# but calls `deps.get --only prod` instead of `deps.get`. This is what
# we do to create the source archive, and we must do the same here,
# otherwise mix(1) complains about missing dependencies (the non-prod
