Unfortunately, binding doesn't provide builds for arm/arch architectures.

I would really like to have arm64 builds for macOS since that is a fairly common platform out there now.

I would also prefer to use this natively. In the meantime, you can install an x86 JVM which will run with Rosetta.

some projects started using zig for easy cross-compilation of C code, eg. https://github.com/lmdbjava/lmdbjava/pull/217 I suspect this would work C++ as well, see https://zig.news/kristoff/cross-compile-a-c-c-project-with-zig-3599

190 should solve this, but for anyone who wants a quick and dirty solution for Apple Silicon:

  1. Clone this repository
  2. Go to buildSrc/src/main/groovy/tool/generator/GenerateLibs.groovy
  3. Apply the following changes so you can target arm64: 
    - def mac64 = BuildTarget.newDefaultTarget(BuildTarget.TargetOs.MacOsX, true)
+ def mac64 = BuildTarget.newDefaultTarget(BuildTarget.TargetOs.MacOsX, true, true)
    - BuildExecutor.executeAnt(jniDir + '/build-macosx64.xml', commonParams)
+ BuildExecutor.executeAnt(jniDir + '/build-macosxarm64.xml', commonParams)
  4. From the repository root, build a native library for arm64: (you might have to install ant) 
    ./gradlew imgui-binding:generateLibs -Denvs=macos -Dfreeetype=true -Dlocal
  5. You'll find the native library under imgui-binding/build/libsNative/macosxarm64/libimgui-javaarm64.dylib
  6. When starting your application pass the following JVM options: 
    -Dimgui.library.path=./path/to/library/folder -Dimgui.library.name=libimgui-javaarm64.dylib
  7. Don't forget to also add the LWJGL native librariess for arm64 to your classpath
