# Cross-compilation environment for the Steam Frame (aarch64), from an x86_64
# host via Debian multiarch: the compiler and Qt's code generators (moc, rcc,
# qmlcachegen) run natively as amd64 builds, the target libraries are the
# arm64 builds. Debian trixie ships Qt 6.8, the series of the Frame's system
# Qt (SteamOS holo 0.4.3: 6.8.0). Adapted from the vrdashboard template.
