# NOTE
# - We cannot unbundle net-libs/libsignal-protocol-c
#   because upstream uses non-API/internal function
#   session_builder_process_pre_key_signal_message
# - The build systems of axc (ex-libaxolotl)
#   at https://github.com/gkdr/axc and libomemo
#   at https://github.com/gkdr/libomemo build static
#   libraries only (*.a) so it is not clear when or
#   how to best unbundle them, either
