tools: Increase the minimal supported CMake version to 3.16 This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system. This is the version that provides most new features and also the one we use in our latest docker image for CI. 2022-05-27 10:10:51 +02:00			`cmake_minimum_required(VERSION 3.16)`
examples: build_system: demonstrate building app with multiple configs This example shows how to use ESP-IDF build system features to build multiple configurations of an app from the same source files. Configurations are set by overriding SDKCONFIG_DEFAULTS variable when invoking idf.py. Related: https://github.com/espressif/esp-idf/issues/5658 2021-04-21 01:11:06 +02:00
