Fails to build on macOS

[fferri]

Contents of config.m:

% ZMQ library filename
ZMQ_COMPILED_LIB = './libzmq.a';

% ZMQ library path
ZMQ_LIB_PATH = '/usr/local/Cellar/zeromq/4.3.4/lib/';

% ZMQ headers path
ZMQ_INCLUDE_PATH = '/usr/local/Cellar/zeromq/4.3.4/include/';

Verify that the above file exists:

>> config
>> ls(strcat(ZMQ_LIB_PATH,ZMQ_COMPILED_LIB))
/usr/local/Cellar/zeromq/4.3.4/lib/./libzmq.a

(no error)

Try to build:

>> make
compile ".../matlab-zmq/src/core/version.c"
Building with 'Xcode with Clang'.

This worked for me (remove the relative path):

ZMQ_COMPILED_LIB = 'libzmq.a';
