What license applies to
1) Qt5Ada?
and (as a separate topic)
2) VTKAda?

The origin works at The Qt Company from which Qt5Ada is derived gives little overt clue:  choice of LGPLv3 or GPLv3 or $459/month EULA license to obtain support.

https://www1.qt.io/licensing-comparison

The origin works at Kitware, Inc. from which VTKAda is derived gives yet another license to ponder:  3-clause BSD-esque

https://gitlab.kitware.com/vtk/vtk/blob/master/Copyright.txt

If you wish to go into the support-for-hire business, then the dual-license choice of
a) LGPL for free
versus
b) EULA for $______/year
would be one of the better balances of increasing mindshare/marketshare but also having a revenue stream.

For my current needs, I am interested in Qt5Ada only without VTKAda.

Btw, thank you very much for this crucial work of bringing Qt5 and VTK to Ada2012!  You are a shining bright beacon of light in the Ada community!  Have you considered that perhaps placing Qt5Ada and VTKAda as 2 repositories on GitHub (tagged by release number) might ease access challenges and cultivate more contact with developers?
