</div>Gavin, interesting idea.<br>
<div class="im"><br></div></blockquote><div>It works well for me, as I build projects on multiple machines with different architectures, and building dependencies as part of the project means I can upgrade dependencies or change their configuration in a single place. The strategy is the one described in the boost CMake docs:</div>
