With Qt5, I was using Qt5::QWindowsIntegrationPlugin to get the dll location to copy it next to my executable.

With Qt6, the same behavior does not work anymore and the only way I found to expose the Qt6::QWindowsIntegrationPlugin target to CMake seems strange to me. Is it due to something missing (bug ?) or is it the right way of doing this with Qt6/CMake ?

find_package(Qt6 COMPONENTS Gui Test REQUIRED)
find_package(Qt6QWindowsIntegrationPlugin PATHS ${Qt6Gui_DIR}) # this line was not needed with Qt5

if (NOT TARGET Qt6::QWindowsIntegrationPlugin)
  message("Without the second find_package, I always end up here")
endif()
