The whole idea of open source is to remove barriers to building on other's code. This isn't cheating. Ignore what school taught you, but make sure you follow the ideals of the license, and try to pass it on if possible. Also, if you import a library, try to actually understand what it does. This is sometimes an unreasonable request (for example libsodium is a gateway to madness/enlightenment) but you should make an effort to understand the code you're importing!
