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