--- Now you're ready to develop in C++ ---

I had a lot of confusion during this, due to the vast lack of resources/info I could find online regarding GDNative C++.
This was one of the most frustrating workflows I've had to deal with, especially if you've never done this, I will save you the migraine:

• The CMD tool you're using, has a huge impact on the project setup. I suggest using a command prompt with internal references to CL.exe, hence why I'm using the Visual Studio CMD
• In the godot-cpp repo, the 'demo' folder is renamed to 'test'. It took some time out of development to figure out, literally. It is functionally the same.
• DON'T MAKE A NEW GODOT PROJECT. Import the test/project.godot file.
• The SConstruct file in the root folder (godot-cpp) is only used for the setup, and the test/SConstruct is used to actually compile your code
• The overall structure of how the project should look, is barely specified. But the godot-cpp is the root, and godot-headers holds all the references to other libraries.
