3# SYNOPSIS
4#
5#   AX_LIB_MYSQL([MINIMUM-VERSION])
6#
7# DESCRIPTION
8#
9#   This macro provides tests of availability of MySQL client library
10#   of particular version or newer.
11#
12#   AX_LIB_MYSQL macro takes only one argument which is optional. If
13#   there is no required version passed, then macro does not run
14#   version test.
15#
16#   The --with-mysql option takes one of three possible values:
17#
18#   no - do not check for MySQL client library
19#
20#   yes - do check for MySQL library in standard locations
21#   (mysql_config should be in the PATH)
22#
23#   path - complete path to mysql_config utility, use this option if
24#   mysql_config can't be found in the PATH
25#
26#   This macro calls:
27#
28#     AC_SUBST(MYSQL_CFLAGS)
29#     AC_SUBST(MYSQL_LDFLAGS)
30#     AC_SUBST(MYSQL_LIBS)
31#     AC_SUBST(MYSQL_VERSION)
32#
33#   And sets:
34#
35#     HAVE_MYSQL
