# This project has three parts:
#   1. The Zephyr app target, which is the minimum additions of
#      any firmware build with Zephyr SO;
#   2. The Rust library made by the user;
#   3. The backend of RART built for Zephyr SO;
# The part 2 and 3 is merged into a library, with the project name,
# and further linked with the Zephyr app target.
