Including ssdeep header files in Xcode project

[localacct]

Hi

I apologize if this is out of topic. I am trying to include ssdeep header files and call the fuzzy hasing functions in my Xcode project and apart from including the "fuzzy.h" header file, I think I need to configure other settings as well as I am getting this error

Undefined symbols for architecture x86_64:
  "_fuzzy_hash_filename", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Would anyone know how to resolve this issue?
