Install arrayfire-rb on macos

[ruggieroguida]

I am struggling to install arrayfire-rb on macos

Arrayfire was installed from here

I am installing the ruby bindings from here

Everything works up to

bundle install

but when I launch

rake install

I receive several

In file included from ../../../../ext/mri/ruby_arrayfire.cpp:5:
/usr/local/include/af/cuda.h:12:10: error: 'cuda.h' file not found with <angled> include; use "quotes"
      instead
#include <cuda.h>
         ^~~~~~~~
         "cuda.h"

Any advice?
