title: error MSB4057: The target "v8" does not exist in the project
body: <p>I'm trying to build V8 as part of <a href="http://www.arangodb.com" rel="nofollow noreferrer">ArangoDB</a> using the official <a href="https://github.com/arangodb/arangodb/tree/devel/3rdParty" rel="nofollow noreferrer">build scripts</a> and following the official <a href="https://docs.arangodb.com/cookbook/CompilingUnderWindows.html" rel="nofollow noreferrer">Windows build instructions</a>.</p>
  
  <p>The compilation fails for all v8* targets (<code>v8-build.bat</code>):</p>
  
  <pre><code>msbuild All.sln /t:v8 /p:Configuration=Release /p:Platform=x64
  msbuild All.sln /t:v8_libbase /p:Configuration=Release /p:Platform=x64
  msbuild All.sln /t:v8_libplatform /p:Configuration=Release /p:Platform=x64
  </code></pre>

  <p>If I open the solution file in Visual Studio, it looks like this:</p>

  <p>I can build <code>v8</code>, <code>v8_libbase</code> and <code>v8_libplatform</code> just fine in VS.</p>
