General ESP-related

• https://github.com/nkolban/esp32-snippets (not maintained, but a great source of examples, Apache 2.0)
• https://github.com/UncleRus/esp-idf-lib (several ESP32 drivers for different peripherals; check license in files)
• https://github.com/tonyp7/esp32-wifi-manager (a pure-ESP32 Wifi manager; MIT)
• https://github.com/khoih-prog/ESPAsync_WiFiManager (ESP32 WiFi manager with an async web interface; arduino platform; MIT)

Other notable Projects

• https://github.com/Edzelf/ESP32-Radio (on ESP32, but with arduino platform; C++; GPL-3.0)
• https://github.com/BM45/iRadioMini (on ESP32, lots of external libraries in use, quite dirty code; NO LICENSE SPECIFIED)
• https://github.com/biologist79/ESPuino (on ESP32, platformio, C++; GPL-3.0; see also https://forum.espuino.de/)

CMake

• https://cliutils.gitlab.io/modern-cmake/
• Pure CMake instead of ESP-IDF's utility

Documentation

• https://github.com/jnikula/hawkmoth (Sphinx plugin that can handle C source files natively)
• Use doxygen with sphinx (really nice, includes the complete setup of a CMake based toolchain up to ReadTheDocs)
• Convert doxygen output to .rst files for Sphinx (alternative to Sphinx's breathe plugin, plain Python-based conversion)

Tools

• cmake language tools (formatter and linter for CMakeLists.txt files, may be useful if/when the CMakeLists.txt contain actual logic, which may be required later; usable with pre-commit)
