title: pybind11 running the test cases
body: <p>I'm trying to learn <code>pybind11</code> and the first Google result is <a href="https://pybind11.readthedocs.io/en/stable/basics.html" rel="noreferrer">this page</a>, where you should be guided towards compiling and running some test cases. From <a href="https://pypi.org/project/pybind11/" rel="noreferrer">this page</a>, I have installed <code>bybind11</code> by:</p>
  
  <pre><code>pip3 install pybind11
  </code></pre>
  
  <p>and I have installed:</p>
  
  <pre><code>sudo apt install python3-dev cmake
  </code></pre>
  
  <p>as instructed in <a href="https://pybind11.readthedocs.io/en/stable/basics.html" rel="noreferrer">the original page</a>. But I don't know how to go to the next step which is to </p>
  
  <pre><code>mkdir build ...
  </code></pre>
  
  <p>and the rest of the steps to compile the test cases. I suppose this should be inside the <code>pybind11</code> installation folder installed via <code>pip3</code>. </p>
  
  <p>my environment is:</p>
  
  <ul>
  <li>Ubuntu 18.04.3 LTS bionic</li>
  <li>Python3 3.6.9</li>
  <li>pip 20.0.2</li>
  </ul>
  
  <p>and my questions are:</p>
  
  <ul>
  <li>where is the path to the presumed test cases where I can follow the rest of <a href="https://pybind11.readthedocs.io/en/stable/basics.html" rel="noreferrer">the tutorial</a> from</li>
  <li>is this the correct/best way to install pybind11? if not what is the recommended method of installation?</li>
  </ul>
  
  <p><strong>P.S.1.</strong> using <code>pip3 show pybind11</code> I realized that I have version <code>2.4.3</code> installed and the installation folder is <code>/usr/&lt;userName&gt;/.local/lib/python3.6/sitepackages</code>. However, inside the <code>pybind11</code> folder there are no test cases as far as I can see. </p>
  
  <p><strong>P.S.2.</strong> From <a href="https://stackoverflow.com/a/56552686/4999991">here</a> I installed via <code>sudo apt install python-pybind11</code> and <a href="https://askubuntu.com/a/54434/535800">from here</a> using <code>dpkg --listfiles python-pybind11</code> I found the installation folder at <code>/usr/lib/python2.7/dist-packages/</code>. Not only there are no test cases in this folder either, but this is also python2.7 which I don't want to use!</p>
