title: LNK1181: cannot open input file 'm.lib'
body: <p>When trying to install a certain Python geophysical toolkit, I get this error:</p>
  
  <blockquote>
    <p>LINK : fatal error LNK1181: cannot open input file 'm.lib'</p>
  </blockquote>
  
  <p>I believe it is due to my use of the MSVC's buildtools. In their <code>setup.py</code> I found:</p>
  
  <pre><code>setup(…, ext_modules=[ Extension(…, […], libraries=['m'], … ])
  </code></pre>
  
  <p>What do I need to change in this <code>setup.py</code>—and related files?—to make this work. IIRC there is a library other than <code>m</code> which I am to use.</p>
