Best way, find both ends of the wire and reroute it around the opening.
This works but is often not acceptable from an estethic viewpoint. Cut the wire on either side of the opening, install junction boxes, then add a wire around the opening. The j-boxes CANNOT be covered with drywall, but could be covered with curtains, pictures, etc.
