Deploying qwindows.dll with CMake

Akapaka

I found out that in Qt5 there was a possibility to deploy plugin in the following way:

add_custom_command(TARGET "app" POST_BUILD
                   COMMAND ${CMAKE_COMMAND} -E copy_if_different
                   $<TARGET_FILE:Qt5::QWindowsIntegrationPlugin> $<TARGET_FILE_DIR:app>)

It doesn't work with Qt6 though:

CMake Error at CMakeLists.txt:17 (add_custom_command):
  Error evaluating generator expression:

    $<TARGET_FILE:Qt6::QWindowsIntegrationPlugin>

  No target "Qt6::QWindowsIntegrationPlugin"

Is there some new way to handle this?
