# 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
