It's quite OK, you're writing to the right place.

It parses the sources and builds a DAG of caller->callee dependencies.

Not exactly.  It is not, for example, concerned about conditional
expressions and the like.  All it's interested in are interfunction
dependencies.

That's not possible: cflow does not see any preprocessor directives,
much like the regular C compiler doe not see them.  They are handled
by cpp before parsing the code.

> 3 - Can I use CFlow as a library in my code?

It is a stand-alone binary (at least now).  So far no provisions have
been made for making it a library.
