rustdesk 1.5.0 and its newer vcpkg pin moved five of the ports the recipe
pre-seeds into vcpkg's downloads:
aom 3.12.1 -> 3.14.1 (rustdesk's overlay port)
ffmpeg 7.1 -> 7.1.1 (rustdesk's overlay port)
libjpeg-turbo 3.1.1 -> 3.2.0
meson 1.8.2 -> 1.9.0
pkgconf 2.5.1 -> 3.0.3
vcpkg found none of the old archives useful and fetched all five itself
mid-build, aom from googlesource. Each new tarball matches the SHA512 in
its vcpkg port.
