feat(mqtt/example): Adds custom outbox example Adds example presenting how to customize esp-mqtt outbox. 2023-05-04 14:22:17 +02:00			`# The following four lines of boilerplate have to be in your project's CMakeLists`

change(examples): switch examples to use a minimal build Currently, several example dependencies rely on the fact that all registered components are added to the build, along with components specified in common requirements. This results in longer build times because even unused components must be built. Switch all examples to use idf_minimal_build to compile only the components actually required by the example.
