title: ReferenceOutputAssembly set to false in vs when loading csproj in cmake
body: <p>When the csproj is loaded, Visual Studio will have the value of ReferenceOutputAssembly false.</p>
  <p>I was expecting the value of ReferenceOutputAssembly to be true
  This is the environment I worked in.</p>
  <p>vs 2019
  csproj classLibrary</p>
  <pre><code>set_target_properties(${BINARY_NAME} PROPERTIES COMMON_LANGUAGE_RUNTIME &quot;&quot;)
  include_external_msproject(test &quot;c:\\test.csproj&quot;
                             GUID &quot;bda34662-9af4-4ad5-be5c-f228db553dc5&quot;
                 PLATFORM AnyCPU)
  add_dependencies(${BINARY_NAME} test)
  </code></pre>
  <p>What to do to change ReferenceOutputAssembly to true?</p>
