Facebook integration - Copy Xcode.Framework

Hi,

I have added this to my .uxl:

          <Require Xcode.Framework="FBSDKCoreKit" />
          <Require Xcode.Framework="FBSDKLoginKit" />
          <Require Xcode.Framework="FBSDKShareKit" />

But I need to know what directive to use to set the directory for where these Frameworks are.

<Require Xcode.FrameworkDirectory="@('path to frameworks':Path)" />

There is a issue now that shows the Frameworks in red, but at least for me it compiles and works.
