What plug-in’s would I need to get my Codea script to run on Windows (in a c-based Lua script GUI)?

Developing Lua scripts to run in a home-grown, very simple c-based Lua scripting environment. I can download .dll’s or create them in C, and our program will load their functions, which I can call in a Lua script. Which dll’s would I need to download in order to get a Codea script to run in this program?
