Description
I tried today to compile our framework with Qt6 Alpha. There I got tons of compile issues as we still using deprecated classes, which are not marked as deprecated via `[[deprecated]]` (we have our compilers configured with warnings as errors). To remove all legacy code I tried to `add_definitions(-DQT_NO_DEPRECATED=1)` to our CMake code, but this isn't working as using `Q_OBJECT` includes code which is maked with the macro `QT_DEPRECATED`, which will be explicitly unset.
Therefore I'm getting compile errors like (Clang 10):

Same with MSVC. Is there a workaround to disable all deprecated code, except `add_definitions(-DQT_DISABLE_DEPRECATED_BEFORE=0x050F00)`?
