DON'T DO THAT, IT'S AWKWARD AF.
The best thing to do is just kinda walk up to someone and say Hi. Or even if someone sit's behind you in a class just turn around and introduce yourself. Even if you don't talk to that person very often it is still good to become familiar with them because that could be good for a future friendship if you don't become friend's right away.
Anyway, sorry for the long reply but trust me it works. (And if it doesn't you probably don't want to be friend with that person anyway).
Wish you Luck, SCL
