Is it possible to make a 3d model compatible with the ue4 mannequin skeleton?

I have a small team of people working on a game, and we want to use the UE4 animation starter pack from the Epic Games store, however, it only works with the UE4 mannequin skeleton. Is there a way to specifically model a character to fit the UE4 mannequin skeleton. If so, does anyone know how?

You can retarget animations to fit your skeleton. Also you can rig your characters with the same skeleton as the UE4 Mannequin ARTv1 in Epic Content,Code Plugins - UE Marketplace

@MMMarcis, does that tool work with any models you import?
