Please split the following files from this package into qt6-multimedia-ffmpeg and qt6-multimedia-gstreamer:

qt6-multimedia usr/lib/cmake/Qt6Multimedia/Qt6QFFmpegMediaPluginAdditionalTargetInfo.cmake
qt6-multimedia usr/lib/cmake/Qt6Multimedia/Qt6QFFmpegMediaPluginConfig.cmake
qt6-multimedia usr/lib/cmake/Qt6Multimedia/Qt6QFFmpegMediaPluginConfigVersion.cmake
qt6-multimedia usr/lib/cmake/Qt6Multimedia/Qt6QFFmpegMediaPluginConfigVersionImpl.cmake

Additional info:
* package version(s) 6.4.0-1
* config and/or log files etc.
* link to upstream bug report, if any

Steps to reproduce:

just install qt6-multimedia-ffmpeg as backend, then create a minimum Qt6 project and edit CMakeLists.txt like this:

# CMakeLists.txt
cmake_minimum_required(VERSION 3.16)
project(media_testing LANGUAGES CXX)
find_package(Qt6 REQUIRED COMPONENTS Core Multimedia)
set(QT_MEDIA_BACKEND ffmpeg)
set(SRCS main.cxx)
add_executable(media_testing ${SRCS})
target_link_libraries(media_testing Qt6::Core Qt6::Multimedia)

then run cmake to configure the project, it will produce:

CMake Error at /usr/lib64/cmake/Qt6Multimedia/Qt6QGstreamerMediaPluginTargets.cmake:95 (message):
The imported target "Qt6::QGstreamerMediaPlugin" references the file

"/usr/lib/qt6/plugins/multimedia/libgstreamermediaplugin.so"

but this file does not exist. Possible reasons include:

* The file was deleted, renamed, or moved to another location.

* An install or uninstall procedure did not complete successfully.

* The installation package was faulty and contained

"/usr/lib64/cmake/Qt6Multimedia/Qt6QGstreamerMediaPluginTargets.cmake"

but not all the files it references.
