#error on ESP8266 and ESPUI, you must define OOM debug option when developping

[MartinMueller2003]

If you are using the Arduino IDE, you can set that option in one of the dropdowns.

[MartinMueller2003]

It looks like it is handled for ESP32 builds. You will need to manually define DEBUG_ESP_OOM as 0 or 1 in the .ino file. This should not be permanently added to the code since it is very platform dependent.
