cleanup: remove unused crate
✓ Descriptive subject! No meaningful explanatory body
What changed, and why it matters
This commit simply deletes an unused third-party Rust crate (cmake) from the project's vendored dependencies. It is a cleanup change with no functional code modifications and no apparent security relevance.
Recommended action
No security action required. Verify that no remaining Cargo.toml or build script still references the cmake crate, though the commit message indicates it was unused.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit removes the entire external/vendor/cmake directory, which contained the vendored cmake-rs crate (version 0.1.54) including its source, Cargo metadata, licenses, and CI files. The commit title and message explicitly state this is a cleanup to remove an unused crate. No firmware code, build scripts, or dependency manifests outside this directory are modified.

-//! A build dependency for running `cmake` to build a native library
-//!
-//! This crate provides some necessary boilerplate and shim support for running
-//! the system `cmake` command to build a native library. It will add
-//! appropriate cflags for building code to link into Rust, handle cross
-//! compilation, and use the necessary generator for the platform being
-//! targeted.
-//!
-//! The builder-style configuration allows for various variables and such to be
-//! passed down into the build as well.
-//!
-//! ## Installation
-//!
-//! Add this to your `Cargo.toml`:
-//!
-//! ```toml
-//! [build-dependencies]
-//! cmake = "0.1"
-//! ```
-//!
-//! ## Examples
-//!
-//! ```no_run
-//! use cmake;
-//!
-//! // Builds the project in the directory located in `libfoo`, installing it
-//! // into $OUT_DIR
-//! let dst = cmake::build("libfoo");
-//!
-//! println!("cargo:rustc-link-search=native={}", dst.display());
-//! println!("cargo:rustc-link-lib=static=foo");
-//! ```
-//!
-//! ```no_run
-//! use cmake::Config;
-//!
-//! let dst = Config::new("libfoo")
-//! .define("FOO", "BAR")
-//! .cflag("-foo")
-//! .build();
-//! println!("cargo:rustc-link-search=native={}", dst.display());
-//! println!("cargo:rustc-link-lib=static=foo");
-//! ```
