White has no weaknesses. Black has two – c5 and c6. White's e2-bishop and knight should be working in that direction, so some reorganization is necessary.
19.Nd2!
The knight is going to c5 via e4 and the bishop is coming to f3.
19...a4 20.Bf3 Ra6 21.Ne4 Be7 22.a3! Preparing Bb4. 22...Ra7?! 23.Bb4! White is close to winning.

19.Nxd4!
The point. Black has no alternative but to part with two pawns for the exchange, after which White's domination of the light squares gives him a clear advantage. Please note the enormous advantage the opposite-colored bishops are to White in this position. (19.Rcc1 c5! would not be better for White)
19...Bxc6 20.Nxc6 Rce8 Probably the only move. 21.Rc1 f5 22.Nd2 Nf6 23.Nxa7 +/-.
