Hi. I'm trying to write a simple MQTT app. I am consistently getting these KConfig errors to do with variables I'm not using, and I have tried to set CMake to ignore these errors by calling -DKCONFIG_ERROR_ON_WARNINGS=OFF when I build. west build -p -b nrf54l15dk/nrf54l15/cpuapp \
applications/Main_App/application \
-- -DKCONFIG_ERROR_ON_WARNINGS=OFF.
Does anyone know how I could get rid of this problem to finish the build?
