# vrdash_bundle_qt()

#
|
|
# Call once, after all dashboards are defined (vrdash_add_dashboard() registers them).
|
|
# 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).
|
|
#
|
|
# Libraries matched by VRDASH_BUNDLE_EXCLUDE are expected on the target system
|
|
# (SteamOS): libc, the C++ runtime and everything tied to the GPU driver / display
|
|
# server. Bundling those would break GPU access, so they always come from the host.
|
|
# Regexes are matched against DT_NEEDED names.
