Expand description
Tells Cargo to pass $path
to the compiler as a -L
flag.
This is equivalent to:
println!("cargo:rustc-link-search=[$kind=]$path");
Examples
Useful for telling the linker where a path can be found.
cargo_emit::rustc_link_search!(
"path/to/ssl/lib/", // same as `=> "all"`
"path/to/ruby/lib/" => "native",
);
or, in case you want it to emit to a custom stream:
let mut stdout = std::io::stdout();
cargo_emit::rustc_link_search!(
to: stdout,
"path/to/ssl/lib/", // same as `=> "all"`
"path/to/ruby/lib/" => "native",
);
