Duo's SSH integration to provide 2FA for SSH

Anybody here using any of the authentication solutions from Duo?

I’m hoping to use their SSH integration to achieve 2FA when logging into SSH (called Duo Unix - https://duo.com/docs/duounix). But they dont have a ready binary for OpenWRT.

Meanwhile, Strykar (https://forum.openwrt.org/u/Strykar) on the OpenWRT forum has created a makefile for it (with + without PAM). Refer to his post: https://forum.openwrt.org/t/testers-wanted-duo-2-factor-auth-for-ssh-and-mosh/48684.

Would someone kindly compile it for Turris Omnia and share it here?
