# which requires a special signature.
#
# CMAKE_BUILD_WITH_INSTALL_NAME_DIR ensures we don't use rpath on Darwin.
#
# NOTE: On Darwin, we only want ncurses in the linker search path, because
# headers are part of libsystem. Adding its headers to the search path
# causes strange mixing and errors. Note that libedit propagates ncurses,
# so we add both manually here, instead of relying on setup hooks.
# TODO: Find a better way to prevent this conflict.
