# Harvest the dynamic-only vcpkg libs (usd 26.3 + tbb 2022.3.0) that the LFS
# runtime bundle is missing: lfs_pod_build.sh archived build/ with
# --exclude='vcpkg_installed', which is exactly where vcpkg puts them.
#
# Runs on a throwaway CPU pod (ubuntu:24.04). Reproduces the ABI of the original
# build: same vcpkg baseline (from LichtFeld-Studio@16047487 vcpkg.json), same
# version overrides, same triplet (x64-linux), same compiler (noble gcc-14).
# Uploads vcpkg_installed/x64-linux/lib/*.so* as usd_tbb_libs.tgz.
