libSDL2 Dependency Issue when setting up on ARM MacOS

[CalixBarrus]

I ran into a problem with getting the dependencies to load when loading yafc for the first time. I found a workaround, but it wasn't obvious, others might possibly into the same problem.

YAFC version 2.5.0

Possibly related to this issue Failed start on apple silicon mac #90

Setting up YAFC on a fresh system, (Apple OSX, ARM), ran into a System DllNotFoundException, even after installing the SDL2 dependencies per the nice OSX install instructions.

Based on the error message excerpt:

Unhandled exception. System.DllNotFoundException: Unable to load shared library 'libSDL2_image.dylib' or one of its dependencies. 
...
  Reason: tried: ..., '/opt/homebrew/Cellar/jpeg-xl/0.11.1/lib/libjxl.0.10.dylib' (no such file), 
...

It seemed like there was a mismatch of the jpeg-xl version installed by brew on my system. jpeg-xl was installed by brew in the directory indicated above, but the file was file libjxl.0.11.dylib. I created a symlink libjxl.0.10.dylib -> libjxl.0.11.dylib, and Yafc loaded without issue (yay!). (This was done per ChatGPT's suggestion, I'm not sure if the workaround will cause any bad behavior, probably not).

Seems like the issue is a mismatch of the jpeg-xl latest version with the dependency of libSDL2_image.dylib.

So, from what I understand, there may be a hard-coded version in libSDL2_image.dylib,
and it needs to be upgraded for jpeg-xl.
The question is how to re-generate the file.
@artanin, could you please provide the instructions to reproduce the binaries from your PR? (#191)

Edit: If we have no say in how brew install SDL2_image is executed, I might have misunderstood the issue.

I just used homebrew to build them then copied them out of the homebrew directory.

@CalixBarrus

I created a symlink libjxl.0.10.dylib -> libjxl.0.11.dylib

So in other words, there was no file [...]/libjxl.0.10.dylib,
but there was a file [...]/libjxl.0.11.dylib?

[CalixBarrus]

On my machine, brew installed version 0.11.1 of jpeg-xl; so there is no file [...]/libjxl.0.10.dylib,

This discussion from SDL_image seems relevant SDL_image issue #450. The discussion gives me the impression that the problem isn't on yafc's side of things.

I remember having some errors like this. Homebrew always runs on latest version and always causes problems with dylib loading. I always copy paste dylib directly into yafc folder or build from source to prevent this kind of issue. It is indeed a big pain for less technical users.
