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."</span></p>

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.</span></p>
