I tried to build our stuff with Vc 0.7 but the VcMacros.cmake from Vc 
master (which has b23418cd6494b90a20204b11f6cdb1f2bfd3877b, "change 
vc_compile_for_all_implementations macro to use normal cmake compilation", 
which makes the small example app build), but that didn't build with our 
code: https://paste.kde.org/pysb0rhgk
