Problem installing IguanaTex on Mac (can’t find `.dylib` file)

I’m trying to install an experimental version of IguanaTex on my Mac. I’m stuck and need some help.

Here are the directions:

  1. install AppleScript (IguanaTex.scpt)

    mkdir -p ~/Library/Application\ Scripts/ cp ./IguanaTex.scpt ~/Library/Application\ Scripts/ 

This worked fine for me.

  1. install IguanaTexHelper (libIguanaTexHelper.dylib)

    sudo mkdir -p '/Library/Application Support/Microsoft/Office365/User Content.localized/Add-Ins.localized' sudo cp ./libIguanaTexHelper.dylib '/Library/Application Support/Microsoft/Office365/User Content.localized/Add-Ins.localized/libIguanaTexHelper.dylib' 

This is where I’m having an issue. . I can’t seem to find the file “libIguanaTexHelper.dylib” anywhere, and I can’t find anything online about it. I’ve already made sure that my computer is showing hidden files. Can someone please help me clear this up?
