Import idl files into Visual Studio (C++)?
<p>I am trying to build an application using the BlackMagic DeckLink SDK. They have a folder in their package which has a bunch of .idl files. The manual says I have to inlcude the idl file. Whats the best way to include this file so I can access its code? </p>

<p>I've tried putting them in the source files folder next to the main class but I still get errors that they can't be accessed.</p>
