Lightroom lua plugin compilation

I would like to compile a plugin in order to deliver it without the source code. There are two versions of the lua compiler with the sdk: one for windows and one for mac. I do not know how to proceed, my plugin has many files which generates tables of functions I do import. An example would be:
 

--<file1.lua>

functions={}

functions.one=function (...<function definition>...

functions.two=function (...<function definition>...


return functions

--<main.lua>

local functions=requiere "file1"
...

• 1. How do I compile both files and make main.luac  import the functions of the compiled file1.luac ?
•  2. If I compile it in windows, will the bytecode work in mac or do I need to make bytecodes for each platform?
• 3. Is there any other way to deliver the code? I know there are some codes for reversing the luac to lua.
