Dependency issue with pvr.vdr.vnsi plugin

I have downloaded and compiled the vnsi plugin from here:
https://github.com/FernetMenta/pvr.vdr.vnsi

I created a zip file of the pvr.vdr.vnsi directory from xbmc/addons/pvr.vdr.vnsi directory.
I attempt to install this addon using the install from ZIP file option in Kodi.

I get this error:
ERROR: CAddonInstallJob[pvr.vdr.vnsi]: The dependency on kodi.binary.global.gui version 5.12.0 could not be satisfied.

I am using Kodi 17.6 Git:Unknown

What should/can I do?

Regards,

Jim
