Micropython v1.19.1 and LVGL v8.3

Hello Armigon,

i thought maybe this would solve the compilation problem with esp32s2 / c2 / c3 / h2 but it´s not the case. The GENERIC_SPIRAM target builds fine, but not the other variants of ESP32.
Build fails with:

fatal error: esp32/clk.h: No such file or directory

it seems the variable CONFIG_IDF_TARGET_* is not set when lv_micropython/lib/lv_bindings/driver/esp32/espidf.h is preprocessed.

I use esp-idf 4.3.3 / Micropython v1.19.1 / and LVGL v8.3
but the problem is same with other esp-idf releases (although i did not test with older esp-idf 3)

The boards GENERIC_SPIRAM and GENERIC_D2WD build fine.
