DLL not found on certain machine with luajit FFI

I have built Game Music Emu from source to use with Love2d. (Note: I am not very familiar with C/C++.)

In lua I load the dll with FFI and on my computer it works great, but when I sent my friend the app for testing, his machine doesn't recognize the DLL.

I sent him the love2d binaries with the libgme DLL included to make sure he didn't just misplace the DLL file. So what he is running is the exact same thing I am running.

My code looks like this:

ffi.cdef[[ ... ]]
local gme = ffi.load("libgme")

This is the exact error my friend gets:

lovegme.lua:4: cannot load module 'libgme.dll': The specified module could not be found.
love2d luajit ffi lua dll

Depending on how libgme is compiled you may have some dependencies that are satisfied on your computer (for example, mingw libraries), but not satisfied on the other computer.

I'd try several things: (1) use the full filename in the load command, (2) use "profile" mode in dependency walker to check what is failing during DLL load, or (3) use the same dependency walker on your machine to see what other DLLs libgme may depend upon and include those in your package/installation as well.
