mysql2 gem fail to install on windows

1. Download if you not using xampp or other binary only mysql in your system.

mysql-5.1.72-win32.zip

2. Extract.

3.  

gem install mysql2 -v '0.3.12' -- '--with-mysql-lib=D:\mysql-5.1.72-win32\lib\opt --with-mysql -include=D:\mysql-5.1.72-win32\include'

4. Enjoy.

* Im using xampp on window8. You can delete the downloaded mysql-5.1.72 from your system after installing the gem. 

Thanks.
