You could write a feature request for that. CMake has a limited support for handling that file but AFAIK, nothing as complete as you would need.
Thanks for your kind words.

@jsulm Hello, I found that I need to use oc and qt for mixed compilation, but I can't add the Foundation framework in cmake. How should I add it?

I checked the information and he said that iOS can only read and write at the location "QStandardPaths::standardLocations(QStandardPaths::DocumentsLocation).last()"
