Here&#39;s a snippet from my ALL_BUILD.vcxproj:<br><br>  &lt;ItemGroup&gt;<br>    &lt;ProjectReference Include=&quot;C:/code/rtsdk/rtmain/build-32-vs10-c30/samples/superellipsoid/superellipsoid.vcxproj&quot;&gt;<br>      &lt;Project&gt;7CCB65D0-CD84-4FA6-AC9A-A69EA772F224&lt;/Project&gt;<br>

<br>Here&#39;s after I run CMake&#39;s configure/generate again:<br><br>  &lt;ItemGroup&gt;<br>    &lt;ProjectReference Include=&quot;C:/code/rtsdk/rtmain/build-32-vs10-c30/ZERO_CHECK.vcxproj&quot;&gt;<br>      &lt;Project&gt;F3C313C6-58A0-45F6-AEDE-8759DE55B380&lt;/Project&gt;<br>
