Published mltbx file fail to run on Mac with Intel processor

[duncanpo]

Installing the mltbx published from a release would fail to run on Intel Mac platform. Packaged MEX files return an "Invalid MEX file" error:

Invalid MEX-file '/.../+libmexclass/+proxy/gateway.mexmaci64': dlopen(/.../+libmexclass/+proxy/gateway.mexmaci64, 0x0006): Library not

'x86_64')),

This is a packaging issue. The shared libraries from all platforms are copied to the same directory before packaging. Libraries from Intel-based Mac and ARM-based Mac have the same names. As a result, One of them will be overwritten.
