# It is a multi-stages docker build with following stages:
# - "esp-opensdk-builder" stage has all the stuff required to build esp-open-sdk
# - "esp-openrtos-bulder" stage takes only the binary toolchain from the first
#   stage + only a few prerequisites to perform esp-openrtos-build

# if set, remove the SDK build directory from the final container
# greate if you only need the xtensa compiler binary file and don't care about anything else (default)
