plasma-workspace COMPILED AND LINKED COMPLETELY and then failed at install:
file INSTALL cannot copy ".../libnotificationmanager/plasmanotifyrc"
to "/etc/xdg/plasmanotifyrc": Permission denied
`cmake --install --prefix` re-roots only RELATIVE destinations. KDE's
KDE_INSTALL_FULL_* paths are absolute, so cmake tried to write into the BUILD
HOST's /etc -- only the host's permissions stopped it from polluting the host
filesystem. DESTDIR re-roots absolute destinations too. Same fix already
applied to kf6-ktexteditor, kde-cli-tools and sddm.
plasma-desktop gets the same fix pre-emptively: it ships /etc/xdg config and
has never been built, so this would otherwise have cost another full cycle.
54 other KDE recipes use the --prefix form but install nothing to an absolute
path, which is why they build clean; left alone rather than churned.
