Subject: Add Qt6 to cmake, build action matrix.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cmake file now takes a QT_VERSION string setting.  The first
character of the string is “6”, then cmake calls find_package
on Qt6…otherwise, it calls find_package on Qt5.

Qt 6.5.2 builds added to the GitHub Actions build matrix.
