Question of library file added

Hi every one.
The example sketch of ESP camera: CameraWebServer_Access_Point.
got error of 'esp_camera.h' No such file or direction , online searched out:

esp32-camera/esp_camera.h at master · espressif/esp32-camera · GitHub

p.1
p.11867×792 65.5 KB

download as : GitHub - espressif/esp32-camera

p0.2
p0.21850×847 83.5 KB

and Sketch - include Library and got error: Specified folder/zip file does not contain a valid library.
why?
thanks
ADAM

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Wild guess here. Perhaps you should try compiling for an ESP32-based board rather than an Arduino Mega.

Thank you .
Ya, I forget to change it back.
