Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.

What is the expected behavior?

I expected it to build the code and flash it onto my esp-32 ovo2640 camera.

What is the actual behavior?

I want to build this code but instead it just keep showing the Error.

The following Error it show is as follow.
CMake Error at C:/Users/whgPd/esp/esp-idf/tools/cmake/build.cmake:266 (message):
Failed to resolve component 'mdns'.

Steps to reproduce.

1. Download Esp-who-master code and only take example/motion_detection -> use this as a main code and delete all of other example code.
   This is where I download the code : https://github.com/espressif/esp-who/blob/master/README.md
2. Download Esp-DL and copy/paste of the component to the esp-who-master/components/esp-dl
   This is where I download the code : https://github.com/espressif/esp-dl
3. Download Esp-camera and copy/paste whole folder to esp-who-master/components/esp-camera
   This is where I download the code : https://github.com/espressif/esp32-camera
4. Set right including path and Build the code. And there is a following error.

More Information.

espressif/arduino-esp32#8740

I have look at this page but it seems that don't related to mine since I used ESP-idf Instead of arduino. I have checked all of the Cmakelist to find is it including mdns but I was unable to find anything related to it.

According to ESP-WHO docs, the master branch of that project is only compatible with IDF release/v4.4 branch. It hasn't been upgraded to IDF v5.x.
Please see espressif/esp-who#240 for the possible workaround.

(The error message generally means that the component hasn't been found. mdns component has been removed from IDF in v5.0 release, and should now be installed via the component manager. I think in ESP-WHO, the developers have simply copied the mdns component into the project tree instead of adding the dependency.)

which path should the component be copied to?and any other file i should config?
