    hello CMake community,<br>
    <div class="gmail-m_7999541161878854554moz-forward-container"><br>
      <br>
      I am experimenting with external projects. I have some files in an
      external project which are generated in `${CMAKE_SOURCE_DIR}`.<br>
      <br>
      <br>
      When I add the external project, however, it is using
      `${CMAKE_SOURCE_DIR}` of the external project.<br>
      <br>
      <br>
      I need `${CMAKE_SOURCE_DIR}` to be relative to the "super build",
      instead of the external project path.<br>
      <br>
      <br>
      Example:<br>
      <br>
      <i>message("${CMAKE_SOURCE_DIR} = /home/user/super")</i><i><br>
      </i><i><br>
      </i><i>ExternalProject_Add(ext1</i><i><br>
      </i><i>    # directory options</i><i><br>
      </i><i>    SOURCE_DIR      "${CMAKE_SOURCE_DIR}/ext1"</i><i><br>
      </i><i>)</i><br>
      <br>
      <br>
      ${CMAKE_SOURCE_DIR}/ext1/CMakeLists.txt:<br>
      <br>
      <br>
      <i>message("${CMAKE_SOURCE_DIR} = /home/user/super/ext1")</i></div></div></blockquote><div> </div><div><i>message("${CMAKE_SOURCE_DIR}/.. = /home/user/super/ext1/..")</i>  which == /home/user/super</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div bgcolor="#FFFFFF"><div class="gmail-m_7999541161878854554moz-forward-container"><br>
      <br>
      <br>
      The desired outcome would be to have the path /home/user/super in
      both messages. </div>
    <div class="gmail-m_7999541161878854554moz-forward-container">How can I do this?</div>
    <div class="gmail-m_7999541161878854554moz-forward-container"><br>
    </div>
    <div class="gmail-m_7999541161878854554moz-forward-container"><br>
    </div>
    <div class="gmail-m_7999541161878854554moz-forward-container">thank you<br>
