Subject: [PATCH] Qt4: Only change timestamp on generated .pro files if content
changes
In qt4_create_translation() use file(GENERATE ...) instead of
file(WRITE ...). This also removes a possible CMP0058 warning
because file(GENERATE) tells the Ninja generator about the files
it provides.
Fixes: #16518
