[Mcrypt-developers] Libmcrypt .lib file?

Hello,
I'm an amateur programmer trying to use libmcrypt in a Windows 7 USB 
device driver.

I have a libmcrypt DLL (taken from PHP), but I'm not sure where to find 
or how to make the .lib file needed to go between the DLL and the 
application.

I've looked extensively online, but have found very little information 
on using libmcrypt outside of PHP or similar applications.

Can anyone on the list offer a suggestion on this subject?

Thanks very much for your help,
Adam
