# (this check is rougly based on and inspired libcurl.m4)
# URIPARSER_CHECK ([DEFAULT-ACTION], [MINIMUM-VERSION],
# [ACTION-IF-YES], [ACTION-IF-NO])
# Checks for uriparser library. DEFAULT-ACTION is the string yes or no to
# specify whether to default to --with-uriparser or --without-liburiparser.
# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
# minimum version of uriparser to accept. Pass the version as a regular
# version number like 0.8.5. If not supplied, any version is
# accepted. ACTION-IF-YES is a list of shell commands to run if
# uriparser 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-uriparser does run ACTION-IF-NO.
#
# This macro #defines HAVE_URIPARSER if a working uriparser setup is
# found, and sets @URIPARSER@ and @URIPARSER_CPPFLAGS@ to the necessary
# values.
#
# Users may override the detected values by doing something like:
# URIPARSER="-luriparser" URIPARSER_CPPFLAGS="-I/usr/myinclude" ./configure
#
