• 8af4b3d (unless the changes in Add target_link_libraries for all Qml Modules #12974 were wanted for some other reason besides Qt 6.6.3 support, otherwise just revert the changes on src/CMakeLists.txt).
• 76cd683 (the CMake stuff is quite changed since this commit but the build.gradle and AndroidManifest.xml changes should be reverted)

These are just what should be reverted from my code, I'm sure there's plenty more in the CMake side of things.
