I've used the following:

----

# Look for mysql via the presence of 'mysql_config' or 'mysql_config5'
#
AC_PATH_PROGS([TOOL_MYSQL_CONFIG], [mysql_config mysql_config5], [],
              [$PATH:/opt/local/bin])AS_IF([test -n "$TOOL_MYSQL_CONFIG"],
      [MYSQL_CFLAGS=`$TOOL_MYSQL_CONFIG --cflags`
       MYSQL_LIBS=`$TOOL_MYSQL_CONFIG --libs_r`],
      [AC_MSG_ERROR([missing program 'mysql_config'; is 'mysql' or 'MySQL-devel'
 installed?])])
AC_SUBST([MYSQL_CFLAGS])
AC_SUBST([MYSQL_LIBS])
AC_PATH_PROGS([TOOL_MYSQL], [mysql mysql5], [],
              [$PATH:/opt/local/bin])

----

Use @MYSQL_LIBS@ and @MYSQL_CFLAGS@ in Makefile.am as appropriate.

It works on CentOS and Fedora with the MySQL packages provided by
either the distribution or from mysql.com, and also for Macports
on Mac OS X (mysql5_config in /opt/local/bin).
