title: Including Armadillo C++ library in a C++ project in Microsoft Visual Studio 2015
body: <p>I'm trying to include the Armadillo C++ library, a linear algebra library, in a C++ project I'm working on, and I'm having a difficult time figuring out how to do so. I'm unfamiliar with how to add libraries to a project in general, so I've been searching for a resource that has step by step instructions, and the best one I could find didn't work for me (<a href="http://codeyarns.com/2013/11/15/how-to-use-armadillo-on-windows/" rel="nofollow">http://codeyarns.com/2013/11/15/how-to-use-armadillo-on-windows/</a>). I followed all the instructions on the web page, and Visual Studio still complains when I put <code>#include &lt;armadillo&gt;</code> and <code>using namespace arma</code> in my code. Does anyone have any idea what I'm doing wrong?</p>
