Rust build dependency that helps you build and link native libraries.

cmakemust be installed and available in the system path.gitif you wish to clone repositories.c/c++build tools.
Before you start, make sure that the cmake project you want to build has install targets setup for the libraries you want to link against. See cmake documentation to learn more.

.compile("rust-cxx-testing");If you are linking against shared libraries, and building for Linux or MacOS, you will need to
explicitly set the @rpath to contain the binaries current directory.
This can be done by adding the following to your final artifact's build.rs:
#[cfg(target_os="macos")]
println!("cargo:rustc-link-arg=-Wl,-rpath,@loader_path");
#[cfg(target_os="linux")]
println!("cargo:rustc-link-arg=-Wl,-rpath,$ORIGIN");
