webchannel? ( qml ) webengine? ( positioning quick ) Without above options enabled cmake tells something like Qt5WebChannel_FOUND set to FALSE. Reproducible: Always
Found more: webengine? ( webchannel ) And these appear to be redundant (there's already "widgets? ( gui )"): webengine? ( widgets? ( gui webchannel ) )
hmm, this is a bit strange because those requirements aren't specified in the relevant CMakeLists.txt files. I.e. the output of this command does not reveal them: grep 'set.*_deps' PySide2/Qt*/CMakeLists.txt
Because it is a dependency of Qt5WebChannelConfig.cmake.
Fixed in version 5.15.7
