<div dir="ltr"><div><div>Hi Jameson, <br><br></div>To specifically address the issue you described, I started to develop an (experimental) module extending ExternalProject and providing some convenience function. <br><br></div>

<div>Documentation is far from being perfect but looking at <br><br>  (1) the tests: <a href="https://github.com/commontk/Artichoke/tree/master/Tests">https://github.com/commontk/Artichoke/tree/master/Tests</a><br></div>
<div>
  (2) the "to be extended/improved" documentation:  <a href="http://cmake-artichoke.readthedocs.org/en/latest/">http://cmake-artichoke.readthedocs.org/en/latest/</a><br></div><div>  (3) example of usage in 3DSlicer: <a href="https://github.com/Slicer/Slicer">https://github.com/Slicer/Slicer</a><br>

<br></div><div>... you should be able to get the idea. <br><br><br></div><div>It basically provide to convenience function:<br><br></div><div>  make_as_superbuild<br><br>  ExternalProject_Include_Dependencies<br><br></div>

<div>allowing to<br><br>    automatically generate the value to pass to either CMAKE_CACHE_ARGS  (or CMAKE_ARGS if needed)<br><br></div><div><br><br></div><div>Ultimately, if the module API stabilizes and turns out to be of general use, it could be integrate into CMake ... <br>

</div><div><br></div><div>Hth<br></div><div>Jc<br></div><div><br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Jun 2, 2014 at 9:00 PM, jmerkow <span dir="ltr"><<a href="mailto:jmerkow@gmail.com" target="_blank">jmerkow@gmail.com</a>></span> wrote:<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I see, that makes a lot of sense.   And in order to pass options from the<br>
'superbuild' build to the 'normal' build you make them options as command<br>
line args in your ExternalProhect_Add command?  i.e.:<br>
<br>
set( proj my_prog )<br>
  ExternalProject_Add( ${proj}<br>
    DOWNLOAD_COMMAND ""<br>
    SOURCE_DIR "${${proj}_Source_Dir}"<br>
    BINARY_DIR "${${proj}_Binary_Dir}"<br>
    CMAKE_GENERATOR ${gen}<br>
    CMAKE_ARGS<br>
        -D${proj}_option1:BOOL=${proj}_option1<br>
        -D${proj}_some_LIBRARY:FILEPATH=${proj}_some_LIBRARY<br>
        ...<br>
    INSTALL_DIR ${proj}/path/<br>
    DEPENDSsd<br>
        ${proj_DEPENDS})<br>
<br>
Is there an easier way to pass all the options to the 'normal' build?<br>
