Optional extension: bundles prebuilt natives from libs/<classifier>/ (every platform directory found is packaged into META-INF/native-libs/). With -DskipNativeBuild=true, cargo is skipped and only libs/ is used. With skipNativeBuild=false (default), runs cargo build --release when a Rust crate is found beside the configured paths; if no crate is found but libs/ already supplied natives into META-INF/native-libs, cargo is skipped automatically. Classifier names must match HpcNativePlatform / os-maven-plugin (e.g. windows-x86_64, linux-x86_64, linux-aarch_64, osx-x86_64, osx-aarch_64). Property yishape.hpc.prebuilt.libs.dir overrides the libs directory (default project.basedir/libs). Runtime override: -Dyishape.hpc.library.path= path to yishape_math_rust. Requires Java 25+ (java.lang.foreign).
