将libmysql.lib文件放置在位于项目目录中的debug文件夹
 
I have visual studio 10 and mysql workbench installed.I have created a new win32 console application project and to include the files done the following:  

in project properties under c/c++ -> general, I have added C:\Program Files\MySQL\MySQL Server 5.6\include  

in linker -> general -> additional library directories I have added C:\Program Files\MySQL\MySQL Server 5.6\lib  

in linker -> general -> input -> additional dependencies I have added libmysql.lib

i have copied libmysql.lib to system32 folder.  
#include<iostream>
#include<my_global.h>
#include<mysql.h>
MYSQL* con=mysql_init(NULL);
MYSQL_RES* result;
the above code gives the following error->
error LNK2019: unresolved external symbol _mysql_init@4 referenced in function "void __cdecl `dynamic initializer for 'con''(void)" (??__Econ@@YAXXZ)

place your libmysql.lib file in debug folder which is located in your project directory
