# A CMake script to run size tool commands supporting OUTPUT_FORMAT and
# OUTPUT_JSON environment variables from within ninja or make or another
# cmake-based build runner.
#
# It is recommended to NOT USE this CMake script if you have the option of
# running the tool directly. This script exists only for use inside CMake builds.

# Main purpose of this script: we can't expand these environment variables in the main IDF CMake build,
# because we want to expand them at CMake target build time not at CMake configuration time
# (so they can change without needing a CMake re-run)
