Having trouble packaging plugin with a luarocks dependency

[aketchum15]

Hello,
I am currently working on a plugin that has to parse large xml files. Originally I was using a lua only library (xml2lua) and just dumping the source into the plugin folder. As I have made significant progress on the logic and functionality of the plugin I would now like to more cleanly express the dependency, and perhaps switch to a compiled library for quicker parsing. I am having trouble understanding how to express a luarocks dependency in the plugin. According to the Packages page on the wiki if a plugin contains a .rockspec file, lazy should automatically build it, but that does not seem to be the case for me. Adding a rockspec file does not trigger lazy to build anything. I have also tried adding the option "build = 'rockspec'" to my plugin's table but I am fairly certain that is for if the plugin itself has a rockspec file. This option causes lazy to present an error:

  Failed (1)
    ● IAR.nvim 3.23ms  start
        ...Local/nvim-data/lazy/lazy.nvim/lua/lazy/pkg/rockspec.lua:160: missing rockspec pkg for IAR.nvim
        This shouldn't happen, please report.

I have attached below how I am listing my plugin for lazy and the directory structure, as it currently is, for my plugin.

return {
    {
        dir = '~/Documents/plugs/IAR.nvim',
        build = 'rockspec',
    },
}
