This is a CMake find module designed to find cargo, the Rust language build tool,
and report its location, version, and channel ("stable", "nightly", "beta").
This allows projects using CMake as their build system to integrate with Cargo, without having to write their own custom logic to identify Cargo and figure out information about what version it is, what channel, etc.
You can use this find module by either 1) adding it to a location in the
CMAKE_MODULES_PATH, or by 2) adding its location to the CMAKE_MODULES_PATH.
Once it's in the modules path, simply add find_package(Cargo) to your
CMakeLists.txt file.
# Replace <CARGO FIND MODULE PATH> with the path to this find module.
set(CMAKE_MODULE_PATH "<CARGO FIND MODULE PATH>" ${CMAKE_MODULE_PATH})This find module is adapted from one I'd contributed for the Pact project, specifically for their reference implementation in Rust. I'd worked on an effort which added a new FFI module, exposing the core mechanisms of the reference implementation to be called by other languages. The Cargo find module enabled us to use CMake to build and install the artifacts produced by Cargo, and made it easier to integrate a Rust codebase with other languages.
