the package `a` links to the native library `a`, but it conflicts with a previous package which links to `a` as well:

Only one package in the dependency graph may specify the same links value. This helps ensure that only one copy of a native library is linked in the final binary. Try to adjust your dependencies so that only one package uses the links ='a' value. For more information, see https://doc.rust-lang.org/cargo/reference/resolver.html#links.
