Finding headers broken in generic project

Finding headers seems to be broken in Generic Project.

Right now, only headers in same folder as  *.cpp file seem to be found. Rest of headers are not found, even if they are part of the generic project.

Issue seems to be caused by commit: "Merge CppTools into CppEditor"

basic example:

make folder structure like this:

testfolder/inc/header.h

testfolder/src/source.c

Try to create generic project in folder "testfolder", and include header and source in it.

Add in source:

#include "header.h"

Code model will say        

error: 'header.h' File not found.
