# Build script for libvncserver (CMake + Ninja) - undocumented dependency
# of x11vnc, see package.toml header for why this port exists.
#
# Deliberately keep the feature surface minimal / no-GTK (project toolkit
# rule): no SDL/GTK/Qt example clients, no systemd, no GnuTLS/gcrypt/SASL/
# FFmpeg/websockets/libsshtunnel. zlib comes from base (/usr/lib); jpeg +
# png come from the Task-5 (M3a) ports already installed at $PREFIX.
#
# illumos socket gotcha (per Task-7a brief + gotcha checklist): sockets.c
# calls socket()/bind()/listen()/accept()/gethostbyname() unconditionally.
# CMake's check_function_exists(socket ...) probe does NOT itself add
# -lsocket/-lnsl to the link line the way autoconf's AC_CHECK_LIB does, so
# without forcing them into the linker flags the final `ninja` link step
# fails with undefined references to socket()/gethostbyname(). Force via
# CMAKE_EXE_LINKER_FLAGS/CMAKE_SHARED_LINKER_FLAGS cache vars.
