Hi, i’m having a very hard time building lvgl project on espidf framework on platformio.
i have lvgl and lvgl_esp32_drivers in component directory as suggested in porting lvgl with esp32 → GitHub - lvgl/lv_port_esp32: LVGL ported to ESP32 including various display and touchpad drivers
These components were shown in the menuconfig. so after all the configurations i build the project and it gave me.

I assumed that i might be using old version of lvgl so i cloned the lvgl 8.3.5 in components, (which is the latest version of now.)
