Compilation of Jiffy 1.1.1 fails on Windows 11

[cynic]

Environment

• x64
• Windows 11 with Visual Studio Build Tools 2019
• Elixir 1.14.3
• Erlang/OTP 25

Steps to reproduce

In Developer Command Prompt,

• Create a new Phoenix project (mix phx.new wut --no-ecto)
• Add jiffy to the mix.exs file (i.e. append {:jiffy, "~> 1.1"} to deps)
• Get deps with mix deps.get
• Build with mix phx.server

Expected

Everything builds and compiles successfully.

Actual

Compilation fails.

Wonder if it's the artifacts rebar config: https://github.com/davisp/jiffy/blob/9ea1b35b6e60ba21dfd4adbd18e7916a831fd7d4/rebar.config.script#L57

Maybe on Windows it should be something like:

diff --git a/rebar.config.script b/rebar.config.script

Yes it is... I was able to make it work by just replacing the {artifacts, ["priv/jiffy.so"]} with {artifacts, ["priv/jiffy.dll"]} @nickva solution seems perfect in this case
