build-firmware.bat

@echo off
REM Build the RS41ng firmware using the Docker build environment.
REM
REM Usage:
REM   build-firmware.bat [config-file.yaml] [extra cmake flags...]
REM
REM Examples:
REM   build-firmware.bat                     - use config.yaml (default)
REM   build-firmware.bat my-tracker.yaml     - use a different config file
REM   build-firmware.bat -DRS41=1            - no config file; pass target flag for the built-in config
REM   build-firmware.bat my-tracker.yaml -DRS41=1
REM
REM The first argument, if it does not start with "-", selects the configuration
REM YAML file (relative to this script's directory). When that file exists, the
REM hardware target is derived from its hardware.type field, so no -D flag is needed.
REM Any remaining arguments are forwarded to cmake. Requires the rs41ng_compiler
REM Docker image (build it once with: docker build -t rs41ng_compiler .).
