#   MOSH_SRC      —— vendor/mosh/src 绝对路径
#   PROTOBUF_SRC  —— vendor/protobuf/src 绝对路径（提供 protobuf-lite 头）

# 依据 src/*/Makefile.am 的 BUILD_IOS_CONTROLLER 分支精确选取源文件。
# 关键：terminal 用 terminaldisplayinit_ios.cc（非 terminaldisplayinit.cc，后者需 ncurses）；
#       frontend 仅取 moshiosbridge/iosclient/terminaloverlay（排除 mosh-client/server/mosh/stmclient）。
