How to use this library in Lazarus

Hello:

 I am new to Lazarus, I had several programs in Delphi using this library and now when trying to compile them in Lazarus,

 I don't know how I should incorporate the ftd2xx.dll library, 

I have included ftd2xx.pas in my project but it doesn't compile and I understand that there must be a way to load the dll that I don't know about.

Thanks
