Failed to link with rustc-link-arg

Problem

[dependencies]
libwebp2 = { version = "0.0.2", features = ["download"] }

cargo build failed

I can successfully build test for libwebp2, but it fails to build when it is used as a dependency for other crates.

The build.rs file of the libwebp2 crate uses the code to link to a static library with an absolute path.

println!("cargo:rustc-link-arg={}", libpath.display());

This looks like an issue with the libwebp2 crate, which appears to have all versions yanked.

cargo:rustc-link-arg causes rustc to pass an additional raw argument to the linker. Passing an absolute path alone here is likely incorrect.

The correct solution is to use cargo:rustc-link-lib=LIB to link the native library.
