Ideally you do it with a press type tool, one cup at a time, with stepped bushings that mate snugly with the cups and the BB shell. For the first cup, one of the bushings is interfaced with the frame to act as a pilot so that the cup stays square and goes in straight, and then for the second cup the other bushing is doing the same while contacting the first cup. This is how the commercial tools tend to work. Making the same thing out of threaded rod and turned or printed bushings is an option if you want a proper tool but don't want to buy one.
Pressfit bottom brackets usually (always?) have a sleeve that bridges the two cups and fits snugly inside a little lip on one or both of them. This makes them more sensitive to going in square during the actual pressing than some other similar pressed-in bike parts. If the second cup gets off-center by much, the sleeve won't mate with it properly as it goes in and can get ruined. For this reason, using traditional home methods for installing pressed parts (blocks of wood and a hammer, vise, threaded rod and washers, etc) can be a little hazardous in the case of pressfit BBs. That's not to say it can't be done.
