EVERYTHING IN THIS FOLDER IS FAKE!
When you pull from gitlab, no symbolic links will be created.
Then execute MakeSymLinks_Windows.bat from Explorer.
The real root source exists as a .cpp file: repo\src\Afterburner\Afterburner.cpp
However Arduino insists upon .ino for their projects, and the file name also
has to match the parent directory name.
If .ino and .cpp live in same directory - double trouble at link time!
Works for PlatformIO, but not Arduino builds.
Ugggh. I hate Arduino IDE (and it's build environment!)
Likewise:
src is linked to repo\src\Afterburner\src
data is linked to repo\src\Afterburner\data
