Xcode can't find XMPPFramework--how do you fix linker errors?

Question

this must be a prevalent problem, but I'd appreciate any help. I have an Xcode 4.2 project that just won't build without errors. The issue is XMPPFramework for iOS. I have followed the directions on the wiki already.

I don't really understand at a deep level what is going on, but Xcode can't find my XMPPFramework (for iOS). Here is the error, and I don't know how to fix it. I have added the path to XMPPFramework in the project and target settings. My XMPPFramework files are located is at the root of my Xcode project already, yet Xcode can't seem to find the files. What is a user header path, framework path, and library search path? I have added the path to XMPPFramework to all of these fields without any benefit. I've used $(inherited) and $(SRCROOT) and checked the recursive button. All my points to whoever can help me fix this.

Nevermind, figured it out. You can't just drag and drop the files into the project. You must copy them into the project folder, then add them.
