Hey all,

Recently, one of the folks working on packaging stuff in Fedora KDE
nearly missed an issue caused by GCC emitting a warning about missing
include dirs:

> cc1plus: warning: /usr/include/qt6/QtCore/6.5.3: No such file or directory [-Wmissing-include-dirs]
> cc1plus: warning: /usr/include/qt6/QtCore/6.5.3/QtCore: No such file or directory [-Wmissing-include-dirs]

I did manage to figure out this meant we needed an additional build
dependency (qt6-qtbase-private-devel, FYI), but it made me think if
there's a reason this shouldn't be an error.

If it's an error, then at least we can evaluate these things and
ensure we have the right build inputs...

Missing an include directory isn't necessarily the problem though, it is the missing headers that aren't present when they are included that would be - and that should trigger a build error for the missing file. What advantage does failing on this warning provide that the failure on the include file missing doesn't?

What do y'all think?
