for cyanoacrylate glue (alpha cyanoacrylate ester) it does indeed get
set by contact with moisture.

CA glues set by polymerization on their own, not like polymers which set by
combining with external stuff (which is why they'll eventually set up in
the tube even if kept in zero humidity). Accelerators are available to
trigger this polymerization. Mere water is not one of them, and a good
thing, too. The instant bonding to skin is not due to water, as any simple
experiment will show.
