It was driving me crazy too, so I started jumping like crazy to the left of the entrance, near the cliff where it kinda seems like you can get a grip and suddenly he reached onto something.
After I got up I tried to find the alternative route, but I didn't find anything obvious, I really don't know the legit way of getting too it.
Right next to the ledge you jumped on is a gap between the building and cliff. You can go through it to circle around to the other side where you can get on the stairs up.
