Include a Kconfig file inside project and libdeps

Hi, excuse me for the question if it seems dumb, i downloaded lvgl_esp32_drivers.
There with Kconfig, i generated the .config i was unsure how to link this file so i create a config.h, located it inside include and i imported it in the main func.
However, the preprocessor define seems to not be linked with the libdeps giving me this kind or error:
lvgl_esp32_drivers/lvgl_tft/ili9341.h:29:27: error: ‘CONFIG_LV_DISP_PIN_DC’ undeclared
How can i properly link this config file so that all project can inherit the preprocessor macros ?
