title: error MSB4019 - MSBUILD looking for imports for non-existing version
body: <p>When I try to build my SSDT project with MSBUILD, I get the following error</p>
  
  <blockquote>
    <p>error MSB4019: The imported project "C:\Program Files
    (x86)\MSBuild\Microsoft\VisualStudio\v11.0\SSDT\Microsoft.Data.Tools.Schema.SqlTasks.targets"
    was not found</p>
  </blockquote>
  
  <p>In my ...\MSBuild\Microsoft\VisualStudio folder, however, I only have V12.0, V14.0 and V15.0. SSDT is found only in V14.0.</p>
  
  <p>How can I make sure MSBuild looks for includes in the right place?</p>
