05/23/2025, 1:31 PMHello , I'd like to figure out a question. When a Compose Multiplatform project that doesn't use any third-party libraries is compiled to the JVM, does the resulting Java executable depend on CPU instruction set-specific libraries — similar to how Skia or JavaFX require separate builds for aarch64 and amd64 platforms? Or can it simply run on any less common instruction set platform as long as there's a sufficiently recent OpenJDK available? Thanks
