How can I setup CPLEX 12.7.1 in XCode 8.3.3 for a C++ code?

I am trying to link CPLEX to XCode for a C++ project. Currently I am using one of the examples provided in the CPLEX package, to ensure any bugs in my code don't affect the setup.

I have followed all of the steps in the following tutorial: http://ift.tt/1p0oCJZ however, I still receive the error message:

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

I have so far been unable to find any tutorials with any additional steps, or a tutorial with the most up-to-date versions of either software.

Any help with this would be hugely appreciated.
