Xcode Cocos-2dx Library Not Found Error

I archived the cocos-2dx project and opened it in other folder but got this linking error.

ld: library not found for -lwebsockets clang: error: linker command failed with exit code 1 (use -v to see invocation)

I think that this error is just because of xcode configuration. Please guide me how I resolve this error. I nothing changed anything in my projects settings.

I am using xcode5.
Thanks
