I know OSX support is a bit bleeding edge, re #24; however, after replacing "2018" with "2014" in FindMaya.cmake the plug-in does start to compile. Unfortunately, I hit a pretty obvious issue that 'maya/MUuid.h' does not exist in the Maya2014 includes.

I'm just starting to dig into the code, and likely am over my head, but I wanted to pose the question and see if anyone thinks this endeavor is possible. Others have mentioned possibly trying to implement a strategy-patterns to help fork behavior within the plug-in for various Maya versions. Any thoughts?

Hmmm... I am blocked now. I was able to comment out the code above just to see if I could compile (expecting run-time errors). I also had to comment out 2 lines in MeshVerticies.cpp because mesh.iSRightHandedTangent() doesn't exist in the older API.
This is the new blocking issue:

Maya2014 might be pre-64bit, so I tried doing an i386 build but the program hits this issue.

So... I might be out of luck.

Thanks for trying this out! Unfortunately supporting 2014 is not a priority for us. Nevertheless let me try to help you out in my spare time :-)
The first problem: where do I download Maya 2014?
IMO the best approach is to drop some features first, and see if the plugin runs at all.
So I would comment out the M3DView.h include in externals, and see where this code is used. Most likely only to refresh the viewport while exporting, not a high priority. AGL is deprecated and replaced by OpenGL and Maya 2014 relies on that (4a1fbefe00db0184aa088eaacdd08a023c666f9f)
The right handed tangent support can be commented out first.
Furthermore I use C++17 and Clang, that didn't exist in 2014, so you will most likely have to use GCC, but that raises a ton of other issues. Then the runtime libraries used might will not be compatible with Maya 2014... All in all this is going to be a major undertaking
But, you can try of course :-)

@ziriax Thanks for sparing some time. I download Maya2014 from ; however, maybe it's only available to people with perpetual licenses. I sent you an invite on LinkedIn so that I can forward you a link.
If it doesn't seem realistic, then maybe it would be best for me to figure out a Maya -> Colada -> GTFL, or an Automation setup, like Maya 2014 -> Maya 2018 -> GTFL.
