-DVAPI=ON fails with No rule to make target when using make %{?_smp_mflags}

That's a weird issue, especially since the CI builds with -DVAPI=ON...
Could you paste the full log somewhere and link it here, and could you maybe also try this with a more recent version of AppStream? (maybe even Git master)

[Mailaender]

You can see the full build log when clicking on the red failed at https://build.opensuse.org/package/show/home:Mailaender:branches:X11:Pantheon/AppStream

[   79s] CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
[   79s]   CMake 3.1.0 or higher is required.  You are running version 2.8.11.2

=> You need a more recent cmake (on !Tumbleweed)...

Apart from that, could you build with a more recent version of AppStream (0.9.5 is current), and check if that issue is still present? The cause is the vapigen step being ordered before the GIR typelib is built, so building without parallel-make will also make this issue disappear (that's only a workaround, of course).

[Mailaender]

If I build with only one parallel thread in make, it works.

[ximion]

Can you please check if that issue is really gone in Git master / with that patch?

[Mailaender]

Fix confirmed.
