There was related discussion in Qt Contributors Summit. Memo: https://wiki.qt.io/QtCS2018_Third-Party_Sources_Policy_and_Security

Check if we need to update 3rd party modules in Qt Tools(contains copies of qmake, qlitehtml, Catch 2)).
Check if documentation of 3rd party component usage is correct and do needed updates. Documentation here: https://doc-snapshots.qt.io/qt6-6.5/licenses-used-in-qt.html
In case of 3rd party component update we need to document the update here: http://code.qt.io/cgit/qt/qtdoc.git/tree/doc/src/legal/licensechanges.qdoc
If there are questions, please contact dedicated R&D owner.
