[webkit-dev] Adding derived sources in Xcode 4.2

[Kenneth Russell]

WebKit developers,

How does one perform the instructions on
http://www.webkit.org/building/debug.html using Xcode 4.2? I've tried
a couple of things locally but am pretty sure I've got it wrong.
(After running build-webkit and changing the Build Products Path and
Intermediate Build Files Path for WebCore.xcodeproj, I still can't
build WebCore independently in Xcode.) Will be happy to help update
the instructions with screenshots, etc.

Thanks,

-Ken
