For what it is worth, I have been running openconnect built from source, I just can't wrap Plasma's GUI around it.

# This wrapper script should never be moved out of the build directory.
# If it is, it will not operate correctly.

That looks familiar.

A workaround for me for now:
1) Build openconnect from source
2) sudo make install
3) sudo ln /usr/local/sbin/openconnect /usr/sbin/openconnect

Now KDE Plasma can connect to my VPN. Yay!
