# is plain qmake6 + make) but unproven, so it is not claimed here.

# No .install file. On current Arch, gtk-update-icon-cache.hook and
# update-desktop-database.hook already refresh both caches, and namcap flags a
# scriptlet that duplicates them. Spec §15 milestone 8 wanted the agent skill
# installed from a scriptlet; it cannot be — that runs as root and the skill
# belongs in the invoking user's home — so Omapresent links it itself on first
# run (Backend::installAgentSkill) from the copy packaged below.
# The binary carries no useful debug symbols for a release package, and the
# split -debug package trips namcap's empty-package rule.
options=('!debug')
# Spec §12's list needed three corrections, each checked against the built
# binary rather than assumed:
#   * qt6-quickcontrols2 is not a package on Arch. Quick Controls 2 and Quick
#     Dialogs 2 ship inside qt6-declarative.
#   * qt6-multimedia is a runtime module. `QT += multimedia` in omapresent.pro
#     links libQt6Multimedia even though no QML file imports QtMultimedia, so it
#     is a runtime dependency as well as a build dependency.
#   * gst-plugins-{base,good,bad,ugly} are not in the playback path at all.
#     Local video is an HTML <video> element (src/renderer/render.js:335)
#     decoded by QtWebEngine's own Chromium stack, which Arch links against
#     ffmpeg and openh264 through qt6-webengine. GStreamer is never loaded.
# No yt-dlp, per the spec.
