Apply path finding algorithm into my internal c++ dll

I have an internal C++ dll that reads XY coordinates source and XY coordinates dest.

Your task is to include a pathfinding algorithm that will allow me to loop it in my current code.

Parameters that we must check:
- path->isWalkable
- path->isPathable
- path->getGroundSpeed

I will provide access to that data you will only have to include the path finding with this parameters.
