DoN's 3D-Pathfinding / Flying-AI system (with full source!)

How do you get the plugin working with a custom-source built UE4 engine? I am using 4.15.2 and put the plugin source into my engine source’s .\Engine\Plugins\ folder and re-generated the project files. However, I get this when attempting to compile:
