Build failure on Qt 5.11 due to qt5_use_modules removal

[prettyv]

Since Qt 5.11 q4wine fails to build with Unknown CMake command "qt5_use_modules" because this macro has been removed. Qt's CMake Macro Reference says about qt5_use_modules: This macro is obsolete. Use target_link_libraries with IMPORTED targets instead

According to this using target_link_libraries and prepending Qt5:: to the module names should generally be enough, although my CMake knowledge is limited.

This issue directly relates to compilation bug during installation of packages q4wine and q4wine-git from AUR in Archlinux.

There is the meaningful part of the output in the terminal:
