@LocutusOfBorg: Mind backporting this fix also to xenial?
The diff between 3.5.1 and 3.5.2 looks small enough to not cause any 
regressions: https://cmake.org/Bug/view_all_bug_page.php?filter=161388

I'm working on porting kodi's build system to cmake and we're and
affected by this.

[Matteo Settenvini]

I produced a patch to fix the issue, complete with test-case. I am
attaching it here, but I will also submit it upstream. It would help, in
the meantime, if it was applied downstream too.
