The other option would be making it explicit in CMake. We just need to
use an exact-match on the kdevplatform version on master. Once we're
branching off this would be changed in the branch back to a >=. Thats
actually pretty easy to do and simply requires increasing the
kdevplatform bugfix number after each incompatible change and then
adjusting the required version in kdevelop's cmakelists.txt.

The benefit of this is that you'd be getting an error very early during
the build as cmake is being re-run and that will error out (I think)
