get copied to the same directories as normal glibc-built binaries which makes MSBuild to overwrite normal ones with musl ones. That essentially breaks SkiaSharp with desktop Mono.

Indeed. That is a very useful observation... 🤦

Is there a way to detect MUSL at runtime so I can correctly load from a different folder?

Thanks for reporting this and sorry for the long delay. I was doing crazy things with MAUI. I see what I did was basically dumb. What would work in a typical case? Would you want to compile for both glibc and musl and have some runtime check (that I am not sure of the best way to do) or have a project property that you set, say <PreferMuslSkiaSharp>true</>?

PreferMuslSkiaSharp looks like a decent solution, yes.

@kekekeks this seems to be a nice solution that does not require any changes to the project files: #1657

It also supports the magic of running anywhere if you copy the output dir. No need for Musl-specific builds.
