@luncliff, Thanks for your PR, this is ci test error log, please take a look:

CMake Error at D:/downloads/tools/cmake-3.27.1-windows/cmake-3.27.1-windows-i386/share/cmake-3.27/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find Gettext (missing: GETTEXT_MSGMERGE_EXECUTABLE
  GETTEXT_MSGFMT_EXECUTABLE)

[luncliff]

For some reason my Windows environment fails to install gettext and gettext-libintl in x64-windows, x64-windows-static. It may take 2~3 more days...

[luncliff]

It took some time to relocate *.desktop files from other kf5* ports
