Having compiling issue for ESP-WHO examples in Eclipse IDE

[MoZen123]

Hi everyone,

The hardware I am using is ESP-EYE,
I have installed IDF version 4 for ESP-32 inside Eclipse and it works well with the examples from ESP-32 espressif template projects.

There are many youtube videos that run these template examples in eclipse,
but for ESP-WHO examples (like camera webserver example), when I import them in Eclipse, they dont compile and I get toolchain error, CMake does not exist error or ninja error...

Is there any resource on how we should run ESP-WHO examples in Eclipse?
WHy inside ESP-who examples we have another IDF folder? which one should we use for Eclipse?
Thank you so much in advance for your assistance.
