Missing library on M1 #21

When trying to use the toolbox on an M1 Mac (under Rosetta), the interface just dies with

Invalid MEX-file '/Users/.../Library/Application Support/MathWorks/MATLAB
Add-Ons/Toolboxes/IPOPT-toolbox/bin/osx/ipopt_osx.mexmaci64': dlopen(/Users/.../Library/Application Support/MathWorks/MATLAB

  '/usr/lib/libasl.3.dylib' (no such file, not in dyld cache)

It seems that libasl.3.dylib should be provided in the toolbox, but it is not being provided. Moreover, per otool, there seems to be hard-coded link to a version in /usr/local/ in libipoptamplinterface.3.dylib.

Or is there a way to install an x86 version of the library using homebrew?

The problem is the fact that linked library have fixed search path and are connected to homebrew. To overcome this problem the script copy_dylib.rb and filter_dylib.rb copy the required library in bin/osx and change the seach path in the dylib. In this case I missed some library. Its difficult to test if all the library are linked correctly because I require a different mac with different configuration. I have redone the toolbox with the password corrected with the same tag 1.1.6. Try It.

This works. Thanks!
