When building with the Netdump library, the IDE generates the following warning: > WARNING: library Netdump claims to run on (esp8266 lwip) architecture(s) and may be incompatible with your current board which runs on (esp8266) architecture(s). Fix the library.properties to call the architecture just "esp8266"
