[swebb2066]

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version, or no changes were necessary.
• Any fixed CI baseline and CI feature baseline entries are removed from that file, or no entries needed to be changed.
• All patch files in the port are applied and succeed.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Exactly one version is added in each modified versions file.

Do we need to do anything to make sure it chooses Qt6 if they are both installed?

e.g. https://github.com/apache/logging-log4cxx/blob/ba4b84682daeec1b50482d7d97c9227ae96be9be/src/main/cpp-qt/CMakeLists.txt#L19

(It's possible/likely that the answer is no, I just want to confirm)

Not as far as I know. The result of find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Core) in ${QT_VERSION_MAJOR} can only have one value, and that is the version that will be used.
