Description
***********

Looks for a MySQL installation in typical locations, or can take in a flag designating where a MySQL installation is found. Sets the variables stated to various attributes of the desired MySQL installation.

In detail, AX_CHECK_MYSQL will automatically look for a MySQL installation in the directories that a mysql source or binary install typically install to. AX_CHECK_MYSQL will throw an error if it cannot find one, and it is required.

AX_CHECK_MYSQL can also check for specific variables passed regarding a location of a MySQL installation.

If a MySQL installation is found, AX_CHECK_MYSQL sets variables regarding the version of MySQL, its architecture (32 or 64 bit), and whether the version supports Plugins.

AX_CHECK_MYSQL_INSTALL will check a designated root directory for a command, plugin, and include directory. If a mysql binary is not found or not found, the IF-FOUND and IF-NOT-FOUND directive will be executed, respectively.

AX_CHECK_MYSQL adds the following flags:

       --with-mysql, for the root of a desired MySQL installation
       --with-mysql-plugin, for the path to the plugin directory of the MySQL installation
       --with-mysql-include, for the path to the include directory of the MySQL installation
       --with-mysql-command, for the path to the binary directory of the MySQL installation
       --with-mysql-source, for the path to a directory containing the source of the MySQL installation

AX_CHECK_MYSQL sets:

       MYSQL to indicate whether MySQL was found or not
       MYSQL_INCLUDES to the include directory (if one exists)
       MYSQL_PLUGINS  to the plugin directory
       MYSQL_COMMANDS  to the mysql executable directory
       MYSQL_ARCHITECTURE to whether MySQL is 32 or 64 bit (32 if 32, 64 if 64)
       MYSQL_VERSION to what the MySQL version is (5.1,5.5, etc)
       MYSQL_PLUGIN_OK to whether MySQL version supports plugins (5.1 or greater)
       MYSQL_55 to whether the version of MySQL is 5.5 or greater
       MYSQL_SOURCE  to the source directory passed by --with-mysql-source
