Looks like the problem is libarchive getting recreated each time.
This seems to be a problem with the response file support in the
Windows branch of Ninja. That branch of Ninja will always relink
any target (in this case cmlibarchive.lib) in the case where the
list of object files exceeds the command line length limit, because
it causes Ninja to use a response file with a different generated
name every time.
I've fixed this by caching the used temporary file names.
And I've updated the ninja.exe.
