In my opinion, I feel that you should just get to know her more and talk regularly with her.(Unless you already do)
Getting hopes up due to one thing and having them crash is always a disappointment.
Just get closer to her for a while but not too close so that she starts to see you as a friend.
Friendly acquaintance/distant friend is best to start off with.
If she is interested in you, obviously you show mutual interest and get closer together(Thats if you like her also)
So TL:DR, I advise you to get closer to her and while not thinking if she likes you or not. Act as a slightly flirtatious guy
