-# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
-# [ACTION-IF-YES], [ACTION-IF-NO])
-# ----------------------------------------------------------
-# David Shaw <dshaw@jabberwocky.com> Jan-23-2005
-#
-# Checks for libcurl. DEFAULT-ACTION is the string yes or no to
-# specify whether to default to --with-libcurl or --without-libcurl.
-# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
-# minimum version of libcurl to accept. Pass the version as a regular
-# version number like 7.10.1. If not supplied, any version is
-# accepted. ACTION-IF-YES is a list of shell commands to run if
-# libcurl was successfully found and passed the various tests.
-# ACTION-IF-NO is a list of shell commands that are run otherwise.
-# Note that using --without-libcurl does run ACTION-IF-NO.
-#
-# This macro defines HAVE_LIBCURL if a working libcurl setup is found,
-# and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary values.
-# Other useful defines are LIBCURL_FEATURE_xxx where xxx are the
-# various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
-# where yyy are the various protocols supported by libcurl. Both xxx
-# and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
-# the macro for the complete list of possible defines. Shell
-# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
-# defined to 'yes' for those features and protocols that were found.
-# Note that xxx and yyy keep the same capitalization as in the
-# curl-config list (e.g. it's "HTTP" and not "http").
-#
-# Users may override the detected values by doing something like:
-# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
-#
-# For the sake of sanity, this macro assumes that any libcurl that is
-# found is after version 7.7.2, the first version that included the
-# curl-config script. Note that it is very important for people
-# packaging binary versions of libcurl to include this script!
-# Without curl-config, we can only make educated guesses as to what
-# protocols are available. Specifically, we assume that all of HTTP,
-# FTP, GOPHER, FILE, TELNET, LDAP, and DICT exist, and (if SSL exists)
-# HTTPS is present. All of these protocols existed when libcurl was
-# first created in version 7, so this is a safe assumption. If the
-# version is 7.11.0 or later, FTPS is assumed to be present as well.
-# FTPS existed before then, but was not yet fully standards compliant.
