Eyelink code not compiling / linking correctly in Matlab 2023b / Silicon version #92

Actually, two issues. The first is, probably simple. The new mglMakeMetal compiles to arm64, but our eyelink library is x86_64 based. So, on compile we get an error:

The second issue seems to be some problem with finding dynamic link libraries. When compiled correctly, the dynamic link libraries could not be found correctly even though there location was specified with the linker flag: -F/Library/Frameworks the eyelink can be run if you put the libraries into the Matlab directory which is still on the dynamic link library list. The error at runtime of any mglEyelink compiled function is that the eyelink libraries cannot be found and therefore the Mex file can't run./
