I would use your configure_file construct if I had a reason to do this. It will work regardless of platform or CMake generator chosen... I would even go so far as to call it "the recommended way."<br>

<div>Hi Kris,</div>
<div><br>
</div>
<div>I have done that by following:</div>
<div>1) use Ninja Generator;</div>
<div>2) include empty "rerun.cmake" file, I put this file into binary dir, so I need a patch;</div>
<div>3) add a patch to Ninja Generator to correctly write dependencies for "build.ninja" from included cmake files, if cmake file is in the binary directory;</div>
<div>4) add a custom commands that check the new files and touching "rerun.cmake" file;</div>
<div>5) once "rerun.cmake" file is touched ninja will rerun cmake;</div>
<div><br>
</div>
<div>Best regards,</div>

<div class="MsoNormal">Hi, I am trying to make cmake reconfigure whenever a certain file is touched. This is because the file ends up listing out a set of directories that need to be built during the build. Currently I do a trick where I use configure file
to write out a file that will never be used but causes the input file to trigger reconfigures.</div>
<div class="MsoNormal">For example:</div>
<div class="MsoNormal"> </div>
<div class="MsoNormal">configure_file( file_i_care_about.txt ${CMAKE_CURRENT_BINARY_DIR}/tmp_file_that_isn’t_used.txt )</div>
<div class="MsoNormal"> </div>
<div class="MsoNormal">Is there another recommended way or is this the best approach. I have tried searching for this but haven’t found anything on it yet.</div>
