Glad it worked.

Note though that a preliminary old-ish CMake port for qtwebchannel has already been done in the super old wip/cmake branch

https://codereview.qt-project.org/q/project:qt%252Fqtwebchannel+branch:wip%252Fcmake+status:merged

Consider trying to work on top of that (aka merge it locally to dev, and the rerun the conversion scripts), because i expect that will end up in less work needed.
