title: How to use external DLLs in CMake project
body: <p>I've been searching over the internet but I couldn't find anything that would answer my question (or I don't know what to search for).</p>
  
  <p>Anyway here's my issue:
  I want to use 3rdParty libraries (.dll files) in my CMake project. Library (<a href="https://github.com/pitzer/SiftGPU" rel="noreferrer">https://github.com/pitzer/SiftGPU</a>) that I want to include is open source and is also available in binary which I would like to use and also uses CMake as build tool if that's relevant. </p>
  
  <p>I hope I was clear enough.</p>
