* Added an option to autosearch for your own installed MySQL as before. Note that default setting is to use the internal MySQL. * You can now build 32-bit even if your MySQL is x64 and vice versa. * Recommended MySQL server version for use with provided MySQL client sources is 5.1.x. * If your server version is different, let CMake autofind and use it instead (check EXTERNAL_MYSQL option) --HG-- branch : trunk
