When a bundled library is Qt WebEngine, the bundler also installs QtWebEngineProcess (plus its libraries) to libexec/, the resources and the en-US/de locales, and points qt.conf at them. The cross image unpacks the arm64 QtWebEngineProcess (its package can't be co-installed with the amd64 one). Experiment for DSH-1: the Frame's system WebEngine (6.7.0, built against FFmpeg 6) can't be loaded. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Adds an install step that makes the install prefix self-contained for all of them

# together: the Qt libraries

|
# (and their non-system dependencies), required Qt plugins and the QML modules the UI
|
|
# imports are copied next to the executable, RPATHs are made relative and a qt.conf is
|
|
# written. Works for native AND cross builds (Qt's own qt_generate_deploy_*_app_script
|
|
# refuses cross-compiled Linux targets, and with a /usr Qt it would bundle glibc too).

|
|
# server. Bundling those would break GPU access, so they always come from the host.
