[cfe-dev] Identifying function calls made to a library

The compiler itself has no idea where your calls point to. It just requires
that you provide declaration for functions and classes you're using and
these are pulled in via includes.
That doesn't mean that you can't detect this yourself. If your library
headers are located inside /mylib you could:
- get the callee from CallExpr
- get the location of the function or member declaration
- and ask SourceManager what file it belongs to
- compare paths.
