# Capture an aarch64 sysroot from a Steam Frame so the cross-build links against
|

# the exact FFmpeg / Vulkan / X11 / PulseAudio SONAMEs present on the device.

# This is the reliable path to a runtime-compatible binary: SteamOS ships
|
|
# different library versions than Ubuntu's arm64 multiarch packages, so linking

# against the device's own libraries avoids "cannot open shared object file" and
|
|
# version-mismatch failures at launch.
