ld: warning: directory not found for option -- deleting derived data and cleaning project don't work [duplicate]

Question

I moved the entire folder for the app I'm working on in Xcode from one place to another on my computer and got the warning ld: warning: directory not found for option followed by a long path.

I followed the accepted answer at Apple Mach-O Linker errors and I don't know what to do but still got the same warning.

EDIT: Here's the message I get, in case it's relevant:

ld: warning: directory not found for option '-F/Users/joel/Development/GayHaiku/../../../Downloads'

EDIT: Turns out that cleaning the project removes the warning--but only until I build it again, and then the warning appears again. I've also tried deleting the derived data, but nothing doing. :(

EDIT: Well, the library search paths and header search paths are empty, but there are several paths in the framework search paths settings. I want to try deleting them, but I'm worried I'll wreck something else, since at this point I'm beyond where I really know what anything actually means; I'm just pressing buttons and keeping my fingers crossed.

Well, it did turn out to be one of the Framework Search Paths. I'm not sure which ones I deleted, and I'm not sure which one was responsible, but if you're having this issue and clearing the Library and Header Search Paths haven't worked, try the Framework.
