baresip | modular SIP User-Agent with audio and video support | TCP library

The previous stackoverflow thread for this is located here. My problem has changed so much that I figured a new thread should be made. I am using CentOS8

I am working on installing a tool called wave-gui and having a real hard time (as you can see from the last thread). My current problem is that a file called cg_config.h is no where to be found when I use the make command (I also get errors 1 and 2). All of the troubleshooting steps that got me to this point are located in the previous thread.

I have copy-pasted the output of the make command below, and the contents of the "main" directory mentioned in the output below that.

I want to implement baresip lib into my Android project using NDK.

I've found up-to-date "bare bones" demo-project in HERE. As in readme I've created some native libs from another repo and placed in "distribution" folder. Project is compiling, installing, working fine. Comparing to Android native sip implementation this lib is just awesome, use it, forget about permission.USE_SIP, its rubish.

Now I want to import baresip into my project, but without Java/Kotlin files, planning to build own. So my steps:

1. Added externalNativeBuild entries to build.gradle
2. Copied cpp and distribution folders to proper places in my structure
3. Invalidate cache and restart

And got exception:

Build command failed.

and ends with
