“Set one's sights on something”in other languages

Same idea, different pictures

English aims like a shooter lining up the sights of a gun, and Spanish turns its prow toward it, poner la proa, like a ship setting course.

French jeter son dévolu sur quelque chose comes from Church law, where a dévolu was a claim laid on a post held by someone unfit for it. Today it's said of anything, or anyone, you've decided to have.
