How to build miniopenvpn used in debug-openvpn.sh?

[scruel]

Hi, I want to build openvpn binaries on Android, however I couldn't find anything related in both OpenVPN3 official repo or here.

I can only find related usages about miniopenvpn, but not build instructions:

Couldn't find miniopenvpn on my phone:

/data/data/de.blinkt.openvpn/cache $ ls
logcache.dat  mgmtsocket

And related file is just empty:
https://github.com/schwabe/ics-openvpn/blob/4473ad1f1bc49c166fb8ab92ee7a7b91c608135e/main/src/main/cpp/minivpn/minivpn.c

@schwabe All related android build issues are pointed to your repo by yourself, so hope you can help a little bit more! Thanks!

I have not used that debug-openvpn.sh script in years. It used to work but I don't think it still works. Current binaries are build using cmake and using the CmakeLists.txt in the cpp directolry.
