1# (this check is rougly based on and inspired libcurl.m4)
2# URIPARSER_CHECK ([DEFAULT-ACTION], [MINIMUM-VERSION],
3# [ACTION-IF-YES], [ACTION-IF-NO])
4# Checks for uriparser library. DEFAULT-ACTION is the string yes or no to
5# specify whether to default to --with-uriparser or --without-liburiparser.
6# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
7# minimum version of uriparser to accept. Pass the version as a regular
8# version number like 0.8.5. If not supplied, any version is
9# accepted. ACTION-IF-YES is a list of shell commands to run if
10# uriparser was successfully found and passed the various tests.
11# ACTION-IF-NO is a list of shell commands that are run otherwise.
12# Note that using --without-uriparser does run ACTION-IF-NO.
13#
14# This macro #defines HAVE_URIPARSER if a working uriparser setup is
15# found, and sets @URIPARSER@ and @URIPARSER_CPPFLAGS@ to the necessary
16# values.
17#
18# Users may override the detected values by doing something like:
19# URIPARSER="-luriparser" URIPARSER_CPPFLAGS="-I/usr/myinclude" ./configure
20#
