Failed to build ics-openvpn in Windows 10

Question

I am try to build ics-openvpn on Windows 10 by Android Studio 4.2.1. I have installed cmake, ndk and sdk and successfully run the first gradle build (Sync project with gradle files). Unfortunately, I am not able to build the main. Below are the logs. It seems it is trying to copy the missing files cmake\skeletonDebug\obj\armeabi-v7a\nopie_openvpn.armeabi-v7a. And, it is also missing "asio.hpp". Where could I find these files?

> Android Version 11 
> Version of the app 0.7.22

Did you run git submodule update --init after cloning the repository?
