I'm using the latest vs code (Version 1.23.1 (1.23.1)) on macOS 10.12. Intellisense is finding header files in arbitrary frameworks inside /Library/Frameworks before includePath which is not how compilers work on macOS.

There are then two problems here:

• Paths in includePath come after macFrameworkPath which is the reverse in macOS compilers
• Arbitrary frameworks are searched in /Library/Frameworks which is unexpected/undesirable

Steps to reproduce

• make a free empty workspace folder
• pick an arbitrary framework in /Library and a header file therein (example QtCore/QObject)
• make another header file of the same name (QObject) in some other folder (/Users/me/bar/QtCore/QObject)
• add that folder to includePath (/Users/me/bar)
• make a .cpp file in the workspace that includes that file with #include "QtCore/QObject"
• observe that the framework version gets parsed not the bar/QtCore/QObject as expected.

I happen to have an Application called Houdini installed I would not expect this location to be searched:

/Library/Frameworks/Houdini.framework/Versions/15.5.717/Resources/toolkit/include/QtCore

Unless I specifically added that framework into my properties.json.
