title: Visual Studio 2017: Speed up C++ IntelliSense
body: <p>I use a header only library in my C++ project.</p>
  
  <p><strong>When I make a change</strong> in my code, Visual Studio starts parsing files in my solution, including the included library.</p>
  
  <p>Since the library is big, parsing it is slow and <strong>I have to wait for a long time until IntelliSense becomes relevant</strong> again.</p>
  
  <p>Is there a way to speed up this parsing, perhaps, by excluding the library from IntelliSense?</p>
  
  <p>This question is NOT a duplicate of <a href="https://stackoverflow.com/questions/42877071/visual-studio-2017-is-too-slow-during-building-and-debugging">Visual Studio 2017 is too slow during building and debugging</a> because it deals specifically with speeding up IntelliSense, which is not touched by the other question, nor it's answers.</p>
