I only know about problems with this w.r.t. Visual Studio 10, as reported just the other day here:<br><br> <a href="http://www.cmake.org/pipermail/cmake/2011-March/043205.html">http://www.cmake.org/pipermail/cmake/2011-March/043205.html</a><br>
<a href="http://public.kitware.com/Bug/view.php?id=11927">http://public.kitware.com/Bug/view.php?id=11927</a><br><br>Are you using VS 10? Or something else?<br><br>You can always write a custom DOWNLOAD_COMMAND if you wish, but ideally, we'd be able to figure out what's triggering this behavior, and then fix it at the root cause...<br>
<br>Give us steps to repro, and if it reproduces reliably, then we can work on a fix.<br><br>Use the small project (downloads/configure/builds/tests nearly instantly) referred to in <a href="http://public.kitware.com/Bug/view.php?id=11927">http://public.kitware.com/Bug/view.php?id=11927</a> (an ExternalProject build of a very small github project) to reproduce with your platform/compilers if possible. A lot easier than doing the same thing with VTK and/or ITK.<br>

I don't know if it's revision specific.<br>
<br>
Sometimes if I change CMakeLists.txt in various directories so that<br>
make will re-run cmake to pickup CMakeLists.txt changes, it triggers<br>
re-downloading VTK & ITK from scratch.<br>
<br>
Is using GIT_REPOSITORY dumber than CVS_REPOSITORY & SVN_REPOSITORY?<br>
If I set UPDATE_COMMAND to "", it never re-downloads. But<br>
GIT_REPOSITORY seems to blow away the downloaded source for an<br>
external project and re-download it, even if the CMakeLists.txt change<br>
is unrelated to to the ExternalProject in question.<br>
<br>
Is there a way to suppress this behavior?<br>
