[CMake] FindQt4.cmake to automatically include QT_USE_FILE?

[Bjørn Forsman]

Hi all,

As far as I can tell, all Qt programs built with CMake must include
QT_USE_FILE after find_package(). So why doesn't FindQt4.cmake simply
include QT_USE_FILE itself? Is there maybe a use case where
QT_USE_FILE is *not* wanted?

Best regards,
