How to compile Cocos2d-x with Box2d support Instead of default Chipmunk

Cocos2d-x engine in some stage i think somewhere in version 2 + Changed its default physique engine from Box2d to Chipmunk .
As new developer that just checking this game engine you might think that Cocos2d-x doesn't support Box2d.
Well it does but the configuration is buried deep in the compiler configuration . why .. i have no idea.
But once you understand where to change you will have the support to Box2d right away .
AFTER compiling the project again .

1. The example will be with Visual Studio 2013 , but its the same in Xcode And Eclipse
   That is in the Preprocessor Definitions .
2. Once you load your new project in Visual Studio right click on you project name
   then properties.

3. In the Popup window you see that is opened go to :
   On the left :
   Configuration Properties -> C/C++ -> Preprocessor  (A)
   Then on the right :
   Preprocessor Definition -> click on the small arrow in the drop list and select "<Edit..>" (B)

4. Once you click on "<Edit..>"  small popup window will be open and called:
    "Preprocessor Definition"
   On the upper Multiline Edit box
   You need to set :
   CC_ENABLE_CHIPMUNK_INTEGRATION=0
   and now you need to add new Preprocessor Definition:
   CC_ENABLE_BOX2D_INTEGRATION=1
   it needs to be like in this image :


5. Now yo must compile the project again , so the new definition you just set will take effect.
