# Build-environment image: contains the toolchain and dependencies only.
# The source tree is bind-mounted at runtime and compiled inside the container:
#
#   docker build -t cloud-point-rpc-dev .
#   docker run -d --name cprpc-dev --network=host -v "$(pwd)":/app cloud-point-rpc-dev
#   docker exec -it cprpc-dev meson setup build-docker
#   docker exec -it cprpc-dev meson compile -C build-docker
#   docker exec -it cprpc-dev ./build-docker/src/cloud_point_rpc_cli config.yml
#
# Use a dedicated build directory (build-docker) so host and container
# builds never share Meson state.
