C++ compile fails in Xcode 5.1

Hi everyone, I'm using Xcode 5.1 to write a C++ program that will read/write and manipulate data created in MATLAB and stored in .mat files. I'm pretty sure I've linked to all the required dylib files and included the appropiate mat.h file.

I get this compilation error:

ld: file not found: mac64/libcilkrts.5.dylib for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Does anyone know what I'm doing wrong here? Thanks.
