The build was working, but I rejected the idea to swap the physics engine since it was a too huge the work to do. You can still find my comit here: https://github.com/AndreaCatania/UnrealEngine/commit/e48b0b32e4d1bf09b9d0b03b6be1478d54a69fde (I’m not 100% sure this was the only work that I did, but it’s the only thing that I’ve). Hope still helpful!
