I am trying to build the esp32-wifi-manager example using ESP-IDF without any changes. But I got the following error.
*** [.pio\build\esp32cam\.pio\build\esp32cam\style.css.S.o] Source '.pio\build\esp32cam\style.css.S' not found, needed by target '.pio\build\esp32cam\.pio\build\esp32cam\style.css.S.o'.
There must be style.css.S file in build directory or error by example?
