title: Adding CMake Includes to the List so it appears in Xocde Project Navigator
body: <p>When CMake is used to generate an Xcode project, the CMakeLists.txt file is included in the Project Navigator window so it is easy to click on and edit. I have written a CMake file that includes some utility functions in CMakeUtils.txt and is then included with <code>INCLUDE(../CMakeUtils.txt)</code>. How can I make this file appear below the main cmake file in the Project Navigator?</p>
  <p>If I add this file as a RESOURCE it will be included with the executable, and that's not right. How do I add a compile-time resource to be listed in Project Navigator but not included with the code?</p>

  <p>For example, the following CMakeLists.txt file would contain the cmake file but not its includes. The associated test.cpp and CMakeUtils.txt files can be empty:</p>
  <pre><code>INCLUDE(CMakeUtils.txt)
  
  CMAKE_MINIMUM_REQUIRED (VERSION 3.17.2)
  
  PROJECT(demo_include)
  ADD_LIBRARY(test test.cpp)
  </code></pre>
