Cannot load IUP with WinLua Binaries

[RussellHaley]

I am attempting to load IUP via the WInLua binaries but get an exception. The Lua53 binries included with the IUP download work without issue.
-- I didn't modify package.cpath because the error is the same either way

l = require('iuplua53')
error loading module 'iuplua53' from file '.\iuplua53.dll':
The specified procedure could not be found.

stack traceback:
[C]: in ?
[C]: in function 'require'
stdin:1: in main chunk
[C]: in ?

With the IUP generated binaries I get this:
C:\Users\russh\lua\iup-3.24-Lua53_Win32_bin> .\lua53.exe

l = require('iuplua');
l

I'm hoping this is just path complications but some brief testing shows it's more complicated than that.

Still requires investigation.
