baresip-studio | baresip library based SIP client for Android | TCP library

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.

Error while executing process C:\Android\sdk\cmake\3.6.4111459\bin\cmake.exe with arguments {--build C:\Android\projects\MyApplication\app.cxx\cmake\debug\armeabi-v7a --target baresip}

and ends with
