# psxrecomp_netplay_libjuice(<recomp-net root>)
#
# libjuice for recomp-net's ICE transport, resolved offline-first.
#
# With RNET_ENABLE_ICE on, recomp-net FetchContents libjuice from GitHub at
# configure time. That download sat outside third_party/deps.manifest, so
# PSX_DEPS_OFFLINE did not cover it: a sealed build (a CI job with no
# network, a player behind a firewall) failed inside the FetchContent subbuild with a
# curl error. Call this before add_subdirectory(recomp-net). It declares the
# same pin from the vendored archive first; FetchContent keeps the first
# declaration of a name, so recomp-net's own FetchContent_MakeAvailable(libjuice)
# builds this copy with recomp-net's own options, and nothing else changes.
#
# Does nothing when the caller already chose a libjuice: RNET_LIBJUICE_ROOT, a
# tree vendored inside recomp-net, or RNET_ICE_BUNDLE_STATIC=OFF
# (find_package). Stops the configure when recomp-net pins a different libjuice
# than deps.manifest, so a submodule bump cannot silently keep the old one.
