How to setting frameworks in Mac OS

[riguz]

Hi, every one:
Recently I switched from Linux to Mac OS, it's glad to find that CodeLite is still available in OsX. However I'm not clear about how to use third-party libraries in CodeLite. Here's my problem:

1/How to use frameworks(eg. SDL2.framework) in CodeLite?
2/Is't possible to use libraries just like the Unix way?For example, build and install libraries to /usr/lib and /usr/include, and then CodeLite just works without any change.

By the way, I found that Xcode is not so user-friendliness, hopes not to use it...

Thanks :>
