We overlook the contribution of other projects.  When we set dependencies
on a project we also export there include paths.  For example,
IProject("application"), IProject("library"),  "application" depends on "library".
When looking for include paths we should look at the dependent project's scannerProvider include paths.
IMHO, there is a flaw in IScannerInfo since it does not allow to make a distinction between
include paths system/compiler builtins and contribution on the command lines(-I ..) , it makes a difference when doing
this, (We address this in the ICPathEntry):

#include <stdio.h>

#include "stdio.h"

Suggestion:

- Search include paths(including dependent projects)
- Fall back to search recursively the project.

I do not quite follow, this:
	ii) Search project regardless of what was 
Why ? if you already find a match.
