From: Josh Steadmon Date: Fri, 21 Mar 2025 22:14:09 GMT Subject: [PATCH v2 3/5] libgit-sys: parallelize build with Cargo's jobserver Message-ID: In-Reply-To: Cargo provides GNU Make flags that can be used to connect to its jobserver for managing parallel builds. They are not automatically passed to any `make` invocations, so let's add that to our build.rs script.
