ардуина не видит библиотеки
нашел готовый проект тестера ESR литиевых батареек на дуйне, решил собрать.
с железом вопросов не было (ну не считая факта, что автор 0 канал АЦП почему-то повешал на землю), а вот сама дуйня при попытке скомпилить код не видит библиотеки:
/usr/share/arduino/arduino-builder -compile -logger=machine -hardware /usr/share/arduino/hardware -hardware /home/user/.arduino15/packages -tools /home/user/.arduino15/packages -libraries /home/user/Arduino/libraries -fqbn=arduino:avr:uno -ide-version=10819 -build-path /tmp/arduino_build_467456 -warnings=default -build-cache /tmp/arduino_cache_886040 -prefs=build.warn_data_percentage=75 -verbose /home/user/Arduino/Impedance_Meter_Sketch/Impedance_Meter_Sketch.ino

т.е. либы есть и распакованы.
ругается хоть на U8glib, хоть на следующий инклайд Adafruit_ADS1015.h если U8glib закомментить.
вопрос: что не нравится этой поделке, и как ее вообще заставить работать?
