title: Using CMAKE how to stop the "Debug" and "Release" subdirectories
body: <p>I have specified my binary output directory with:</p>
  
  <p><code>set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/bin)</code></p>
  
  <p>Unfortunately, Visual Studio adds <code>Debug</code> and <code>Release</code> directories.</p>
  
  <p>I do not want these.</p>
  
  <p>The <a href="https://cmake.org/cmake/help/v3.4/prop_tgt/RUNTIME_OUTPUT_DIRECTORY.html#prop_tgt:RUNTIME_OUTPUT_DIRECTORY" rel="noreferrer">documentation for CMAKE</a> says:</p>
  
  <blockquote>
    <p>Multi-configuration generators (VS, Xcode) append a per-configuration subdirectory to the specified directory unless a generator expression is used.</p>
  </blockquote>
  
  <p>But I am not sure exactly what that means.  </p>
  
  <p>How can I get Visual Studio to <strong>not</strong> add those directories?</p>
