Description

Currently libjpeg (libjpeg.dylib) cannot be built on Apple platforms. This becomes an issue when trying to incorporate it into applications on Apple platforms, so we will address this properly to make it buildable.

Also, with this change, it will be possible to build properly with Emscripten, so we will not exclude it.

Check:

$ mkdir "build"
$ (cd "build" && cmake .. -DJPEGXL_ENABLE_JPEGLI_LIBJPEG=ON && make -j"$(sysctl -n hw.logicalcpu)")
$ nm -gU ./build/lib/jpegli/libjpeg.62.dylib
