title: How to include python-dev in buildroot?
body: <p>I'm making a buildroot for my raspberrypi3 for a school project.</p>
  
  <p>I've made a buildroot with everything from python included because i want to use <a href="http://webiopi.trouch.com/" rel="nofollow noreferrer">WebIOPi</a>. A buildroot has been done and the image has been written on the SDCard.</p>
  
  <p>Now when I want to install it on the buildroot device it asks for python-dev, wich is not included by buildroot. With further research I've only found <a href="https://pypi.python.org/pypi/dev" rel="nofollow noreferrer">this</a>. Thats a python-dev0.4.0 but i think there's a much recent version on my virtual ubuntu16 os.(main os is windows 10, so need image to use win32diskimager)</p>
  
  <p>But I don't know how to implement this in the python buildroot packages. I've already read the manuals from buildroot, it's kinda confusing for me...
  I've already tried to make a directory named 'python-dev' in the buildroot/package directory (ubuntu os) but with no succes.
  This is what i've got so far:</p>
  
  <p>buildroot/package/python-dev:</p>
  
  <ul>
  <li>config.in</li>
  <li>python-dev.mk</li>
  </ul>
  
  <p>in the config.in file:</p>
  
  <pre><code>config BR2_PACKAGE_PYTHON_DEV
  bool "python-dev"
  help
  </code></pre>
  
  <p>in the python-dev.mk file (copied from libconfig):</p>
  
  <pre><code>################################################################################
  #
  # python-dev
  #
  ################################################################################
  
  PYTHON_DEV_VERSION = 0.4.0
  PYTHON_DEV_SOURCE = dev-0.4.0.tar.gz
  PYTHON_DEV_SITE = https://pypi.python.org/packages/53/34/e0d4da6c3e9ea8fdcc4657699f2ca62d5c4ac18763a897feb690c2fb0574/dev-0.4.0.tar.gz
  
  PYTHON_DEV_LICENSE = Python software foundation license v2, others
  PYTHON_DEV_LICENSE_FILES = README
  
  PYTHON_DEV_SETUP_TYPE = setuptools
  
  PYTHON_DEV_DEPENDENCIES = libconfig boost
  
  $(eval $(python-package))
  </code></pre>
  
  <p>When I run a make menuconfig and search for python-dev, it's not there...
  I hope someone could help me with this.</p>
  
  <p>If there's an easier way, it's pretty much welcome.</p>
  
  <p>Thank you in advance.</p>
