# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
#                       [ACTION-IF-YES], [ACTION-IF-NO])
# ----------------------------------------------------------
#      David Shaw <dshaw@jabberwocky.com>   May-09-2006
#
# 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 guess what protocols are available,
# or use curl_version_info to figure it out at runtime.
