title: Xcode linker Directory not found for option
body: <p>Xcode 4 is throwing me a warning about directory not found for option '-L/Users/t2wu/Documents/blah blah'. Yes it shouldn't be found because I removed it. I remove the directory and I also removed the directory setting in both the target and the project library search path. I also remove the .a file which I was linking before from the "Link binaries with Libraries". It compiles fine, it just gives me the warning. Why is it still having the -L flag?</p>
