Ok, thanks for the info, I will follow that up.

We do provide the latest kdevelop5 version in KDE:Extra for Leap 15.0 and 42.3
as well. (AFAICS, Leap 15.1 does have llvm7 as default already but without that
change so far, apparently it comes from SLE, not Factory)

We can conditionally leave the dependency in for the older versions though, so
it's not really necessary to release an update with this change from our side I
think.

OTOH, kdevelop5-plugin-clang-tidy needs clangX anyway (for the clang-tidy
executable), and will be included in kdevelop5 5.4 AFAIK (currently it's
released separately). Although it's probably not necessary to add a Requires
for that, a Recommends at most should be enough IMHO.
