# Readline_ROOT_DIR Set this variable to the root installation of
# readline if the module has problems finding the
# proper installation path.
#
# Variables defined by this module:
#
# READLINE_FOUND System has readline, include and lib dirs found
# Readline_INCLUDE_DIR The readline include directories.
# Readline_LIBRARY The readline library.
