rosdep
rosdep install is a command used in ROS (Robot Operating System) to install system dependencies for software you want to build from source.
- Reads the package manifest (package.xml) to identify and install missing dependencies.
- Rosdep uses the package management system of your operating system to install them.
Rosdep calls apt install.
- For mac, does it call brew install?
This ensures that all required libraries, tools, and other system packages are available for building and running the ROS2 packages.
