# This script is used to generate .gni files and files in the

#
# Every time the upstream source code is updated this script must be run.
#
# Usage:
# $ ./cmake_update.sh
# Requirements:
# Install the following Debian packages.
# - cmake3
# - yasm or nasm
# Toolchain for armv7:
# - gcc-arm-linux-gnueabihf
# - g++-arm-linux-gnueabihf
# Toolchain for arm64:
# - gcc-aarch64-linux-gnu
# - g++-aarch64-linux-gnu
# 32bit build environment for cmake. Including but potentially not limited to:
# - lib32gcc-7-dev
# - lib32stdc++-7-dev
# Alternatively: treat 32bit builds like Windows and manually tweak aom_config.h
set -eE
# sort() consistently.
