Walkthrough

A new --cmake-arg/-c command-line option has been added to the ros build command in platform_cli/groups/ros.py. This option accepts multiple string values and allows users to pass additional CMake arguments to the underlying colcon build invocation. The provided CMake arguments are appended to the existing --cmake-args -DCMAKE_EXPORT_COMPILE_COMMANDS=ON segment within the generated build command string, positioned before any debug symbols configuration is applied.

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title lacks the required Shortcut task tracker link (e.g., SC-XXXX) and does not include a scope for the package, which are specified requirements.	Update the title to follow the format: 'feat: [SC-XXXX] (scope) add ability to specify extra cmake args' with the appropriate Shortcut task ID and package scope.

✅ Passed checks (3 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Documentation	✅ Passed	The custom check for documentation updates applies specifically to changes to ROS nodes and requires updating design.md files. This pull request modifies platform_cli, a CLI tool, not a repository containing ROS nodes. The change adds a --cmake-arg/-c option to ros build, which is a CLI tool enhancement not modifying ROS node implementations, parameters, topics, or services.
Leaked Secrets	✅ Passed	The PR adds a --cmake-arg option for local builds only, with no mechanism to pass these arguments to Docker builds. Proper secret handling via Docker buildx secrets is already in place.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}
