Linking OpenCV library in Xcode 4?

I've been having trouble compiling my own OpenCV iOS project. I started with a simple command-line app target and I've now added an iOS app target. The problem is that my iOS target produces the following linker error:

ld: library not found for -lcv

collect2: ld returned 1 exit status

Command

/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-g++-4.2

failed with exit开发者_运维百科 code 1

I'm not sure where the flag, -lcv is coming from, as I haven't set it as any of the settings in my project's "Build Settings". I've downloaded a demo OpenCV iPhone project that compiles perfectly fine, and I've tried to copy the build settings from this project but I can't see what's different!

Thanks very much for any help.

Try adding in the project settings the path exact of the library since : /User/..... important: only ONE ""
