Problem when building the Juce's AU Plugin Demo

I everyone, 


I'm trying to build the Juce Audio Unit plugin demo, but I get 20 Errors, 


Here is a screen :




I think that I miss a library that include "Audiocomponentplugininterface" or something else...


I've tried during 4 hour different core audio sample classes, it doesn't work...

My folder is in my application/Content/Developer/Extras.



Thanks in advance and sorry for my english, I'm french.
