Looking for a crossplatform library that works with zip archives

I'm looking for a crossplatform library that works with zip archives

- It is desirable (but not necessary) the library to be Qt-compatible
- It should be cross platform (or at least work on Win and Mac)
- Preferably LGPL or other license that allows to use it in close source project, but please post any other commercial library if it is exist

maybe this link helps you.
