Stumped using .c and .h files for esp32 AP & OTA capability

I'm a fledgling coder and do well with what I know. Unfortunately I don't know how to work with the .c and .h files provided in the following link: ESP32-OTA-Webserver

I'm trying to have it so I can connect directly to esp32 (AP mode) to upload a new sketch (OTA).
This appears to be exactly what versamodule has done in his coding. However I don't know what to do with the files he provides.

Would be great if the AP IP address could be set in the sketch as a parameter. This way it can be changed for different esp32 modules.

Thank you for the assist!!

It looks like its meant to be used with ESP-IDF.
This is different from the Arduino ESP32 core, it uses its own build system.

PieterP - That makes sense. Thank you very much for pointing that out! I'll continue trying with the arduino core OTA.
