title: WEBP support not installed error with Pillow included in Anaconda
body: <p>I have written a small code to open webp image in the Anaconda prompt. </p>
  
  <pre class="lang-py prettyprint-override"><code>from PIL import Image
  im = Image.open('test.webp')
  </code></pre>
  
  <p>It causes the following error:</p>
  
  <pre><code>C:\ProgramData\Anaconda3\lib\site-packages\PIL\Image.py:2655: UserWarning: image file could not be identified because WEBP support not installed
    warnings.warn(message)
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "C:\ProgramData\Anaconda3\lib\site-packages\PIL\Image.py", line 2657, in open
      % (filename if filename else fp))
  OSError: cannot identify image file 'test.webp'
  </code></pre>
  
  <p>The same code works fine in python-3.7.2-amd64 installed in another directory with Pillow 5.4.1.  </p>
  
  <pre><code>Package    Version
  ---------- -------
  Pillow     5.4.1
  pip        18.1
  setuptools 40.6.2
  </code></pre>
  
  <p>The above code causes the same error in Anaconda prompt, Spyder and Jupyter Notebook.  Still the same error even after reinstallation the Anaconda or trying on the different PC.</p>
