In top-level builds, when configuring qtsensors, the directory of
FindWMF.cmake isn't in ${CMAKE_MODULE_PATH}, this makes CMake couldn't
find WMF.
On Windows, QtMultimedia requires WMF. If WMF couldn't be found,
QtMultimedia will also be treated as NOT FOUND.
QtSensors has an optional dependency to QtMultimedia. If QtMultimedia
couldn't be found, CMake will warn.
Copy Find*.cmake to ${QT_BUILD_DIR}/lib/cmake/Qt6, to make sure these
files could be found by CMake.
