160 # Checks for libcurl. DEFAULT-ACTION is the string yes or no to
161 # specify whether to default to --with-libcurl or --without-libcurl.
162 # If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
163 # minimum version of libcurl to accept. Pass the version as a regular
164 # version number like 7.10.1. If not supplied, any version is
165 # accepted. ACTION-IF-YES is a list of shell commands to run if
166 # libcurl was successfully found and passed the various tests.
167 # ACTION-IF-NO is a list of shell commands that are run otherwise.
168 # Note that using --without-libcurl does run ACTION-IF-NO.
170 # This macro #defines HAVE_LIBCURL if a working libcurl setup is
171 # found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
172 # values. Other useful defines are LIBCURL_FEATURE_xxx where xxx are
173 # the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
174 # where yyy are the various protocols supported by libcurl. Both xxx
175 # and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
176 # the macro for the complete list of possible defines. Shell
177 # variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
178 # defined to 'yes' for those features and protocols that were found.
179 # Note that xxx and yyy keep the same capitalization as in the
180 # curl-config list (e.g. it's "HTTP" and not "http").
182 # Users may override the detected values by doing something like:
183 # LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
185 # For the sake of sanity, this macro assumes that any libcurl that is
186 # found is after version 7.7.2, the first version that included the
187 # curl-config script. Note that it is very important for people
188 # packaging binary versions of libcurl to include this script!
189 # Without curl-config, we can only guess what protocols are available,
190 # or use curl_version_info to figure it out at runtime.
