That plays into one of the reasons why there's not a lot of Lua libraries: they're mostly ecosystem-specific. There's quite a few Lua libraries for WoW that aren't inherently tied to WoW, but they aren't packaged in a way that makes them usable anywhere else. People writing code for a specific program that happens to use Lua generally can't use libraries from LuaRocks, so there's no reason for them to care about LuaRocks in any way.

Sadly I'm not sure that there's really any solution to this problem other than just accepting that an embedded language will have a very fragmented ecosystem.
