use cmSystemTools::MoveFileIfDifferent()
This is better than doing CopyFileIfDifferent() followed by RemoveFile() in
two ways:
- it is more efficient, as it avoids disk I/O for the data, even if the
files here are usually small
- it is atomic, so an abort during the copy will not leave a destination
file
with partial data behind
