ADDITIONAL CONTEXT

Add any other context about the problem here. Unfortunally I couldn't figure out why the build-process uses the CXXFLAGS when compiling (only this) file.. I figured out that this compiler option was only set by "pio-tools/add_c_flags.py", but I don't find why this was applied when compiling "Tasmota/lib/libesp32_lvgl/lvgl/src/widgets/lv_checkbox.c". It seams that this file was compiled in C++ Mode even it is a c file ??

(Please, remember to close the issue when the problem has been addressed)

I will check, but I don't remember seeing this warning

I'm seeing the warning all the time when building for ESP32, and haven't worried about it :smile_cat:
