plasma-framework build error (threadweaver)

[Marco Martin]

Hi all,
today with up to date kdelibs, extra-cmake-modules and plasma-framework i get 
the following build error:

http://paste.opensuse.org/35600424

it seems build goes fine if i do the following change in kdelibs:
http://paste.opensuse.org/74808056

but i don't think it's correct to remove every reference to threadweaver from 
KDELibs4Config.cmake ?
what would be a correct way to fix this?

Cheers,
Marco Martin
