# SYNOPSIS

#

#   AX_LIB_MYSQL([MINIMUM-VERSION])

#

# DESCRIPTION

#

#   This macro provides tests of availability of MySQL client library

#   of particular version or newer.

#

#   AX_LIB_MYSQL macro takes only one argument which is optional. If

#   there is no required version passed, then macro does not run

#   version test.

#

#   The --with-mysql option takes one of three possible values:

#

#   no - do not check for MySQL client library

#

#   yes - do check for MySQL library in standard locations

#   (mysql_config should be in the PATH)

#

#   path - complete path to mysql_config utility, use this option if

#   mysql_config can't be found in the PATH

#

#   This macro calls:

#

#     AC_SUBST(MYSQL_CFLAGS)

#     AC_SUBST(MYSQL_LDFLAGS)

#     AC_SUBST(MYSQL_LIBS)

#     AC_SUBST(MYSQL_VERSION)

#

#   And sets:

#

#     HAVE_MYSQL
