These files are coming from the official mysql distribution you're working with. Just look for the libmysql.dll file and make sure you put it somewhere in the dll search path of your project executable. When your project must be able to use different mysql protocols you can rename the libmysql.dll file to libmysql<version>.dll as you mentioned them above.
