--- Comment #3 from Duncan <1i5t5.dun...@cox.net> --- Likely related: kwayland commit de442e4a9: Install Client headers in a dirs hierarchy matching the C++ namespaces which references https://mail.kde.org/pipermail/kde-frameworks-devel/2022-January/120608.html . Quoting the commit: This auto-magically worked with KF5 because <prefix>/include/KF*/ was always added to the targets interface include dirs by ECM (for compatibility with KDE4?). >From the symptoms it seems ECM isn't doing that any more even on KF5. (Looking at new updates and came across that. Hopefully it means the others are caught now too and are fixed (or being fixed), and I'll catch them as I look at more updates. Maybe I'll be able to RESOLVED/FIXED, or at least narrow down the list of affected builds a bit, with my next comment.) -- You are receiving this mail because: You are watching all bug changes.
