dl_lib.h missing with ESP32 Cam

[hoahoctro]

Im compiling a customized sketch for ESP32 Cam, but the IDE shows error: dl_lib.h: No such file or directory found

I have searched but havent had the guide to fix it, please help. Thanks

I used both these sketch and they all show the dl_lib missing error:
