# - Try to find readline include dirs and libraries
#
# Usage of this module as follows:
#
# find_package(Readline)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# 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
# GNU_READLINE_FOUND Version of readline found is GNU readline, not libedit!
# LIBEDIT_FOUND Version of readline found is libedit, not GNU readline!
# Readline_INCLUDE_DIR The readline include directories.
# Readline_LIBRARY The readline library.
# GNU_READLINE_LIBRARY The GNU readline library or empty string.
# LIBEDIT_LIBRARY The libedit library or empty string.
