# - 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.
