Supported Targets	ESP32

Networking component dependency

This test application checks the list of components included into the build when:

• esp_netif component is added to the build.
• lwip component is added to the build.

The test checks that driver components are not included in the build

Using this test app

• Remove the build artifacts idf.py fullclean
• Choose the component to test (either esp_netif or lwip)
• Build the project idf.py build

Troubleshooting

If you get a build error in this example, please check there's no dependency from the tested component (either esp_netif or lwip) to any defined driver component.

Please open the project CMakeLists.txt to view the expected dependencies and driver's components that must not be included in the list:

• CMake variable driver_components contains list of driver's components
• CMake variable expected_build_components contains list expected dependecies

Note that this project creates component_deps.dot, a simpified dependecy graph that could be used to display and troubleshoot component dependencies.

Note that this test is executed for one target only in CI (ESP32), but shall work correctly for all IDF supported targets.
