title: LLVM Visual Studio Integration Failed
body: <p>I'm trying to integrate LLVM with Visual Studio 15 2017, however I seem to be unable to get it to work. When running the LLVM installer after Visual Studio has been installed, I get a command prompt with the following error:</p>
  
  <blockquote>
    <p>Installing MSVC integration...<br>
    Failed to find MSBuild toolsets directory.
    MSVC integration install failed.<br>
    Press any key to continue . . .</p>
  </blockquote>
  
  <p>After some research online, I found <a href="https://stackoverflow.com/a/49501558/3067678">this</a> SO link which has lead me to believe that the LLVM installer does not know how to install for VS15. As such, I tried installing the toolset found <a href="https://github.com/plasmacel/llvm-vs2017-integration" rel="nofollow noreferrer">here</a> manually. Now, I can see LLVM listed as a toolset in Visual Studio:</p>

  <p>However, when I choose it as an option and try to compile a simple "Hello World" program, I get the following error:</p>
  
  <blockquote>
    <p>error MSB8020: The build tools for LLVM-vs2017 (Platform Toolset = 'LLVM-vs2017') cannot be found.<br>
    To build using the LLVM-vs2017 build tools, please install LLVM-vs2017 build tools.<br>
    Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Retarget solution".</p>

  <p>Is there something I am doing wrong here, or some step I missed when trying to get these two tools integrated?</p>
