Building SDK or Helpcontent or translations is not affected by
incremental builds usually. And of course you won't lose dependencies
by copying multiple stuff at once. You might waste some time doing i/o
by shoving around files that weren't changed, but for stuff like sdk
documentation that is created by doxygen that injects timestamps into
every file (i.e. stuff is always changed) this doesn't matter from my
Same for help. Changing help means regenerating index, so everything
will be looked up anyway, so having it in the filesystem cache doesn't
hurt for linux. But copying this in one go will help the build on

That won't be the case. Copying more stuff at once for those will not
mess with dependendencies. It might result in more disk-activity, but
the areas where it matters most (sdk, help, translations) aren't
touched in everyday development, aren't even enabled in everyday

No, not preventing. The code that identifies candidates that could be
handled by patched make just need adjustments to match.
But this is only a workaround to hide the problem with the many
processes. Removing the tons of "touch" calls would be real
improvement. And I don't see a reason why a stuff need to depend on a
touch-pseudo-target the created object itself.

Well, even if rhetorical: If that turns out to be a problem: Yes.
Still preferred over spawning zillions of processes on windows.

Which in effect it is. After slowcheck it is more or less separate.
Having it after the build as separate /manual step is pointless, as
then you woudn't only need to sign, but also rebuild the installsets.
And building installests on windows also is slow. So I object to
making it an "after make finished" thing.
