On non-windows platforms, we use the "-p" parameter of install(1) to preserve the last modification timestamps of files. On Windows the use of copy does not preserve them. As a cross-platform solution, this patch introduces a simple built-in install command in qmake to copy files. Task-number: QTBUG-59004 Change-Id: I3064d29a2b8c7b009a1efbf8f00b84c079ea5417 Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@qt.io>
