Preserve last modification timestamps of installed files
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
