title: "apt-get: command not found" issue raspberrry pi os built using Buildroot
body: <p>I have built a sdcard.img for raspberry pi using Buildroot. When I run apt-get command it throws error "apt-get: command not found". I did not find apt-get/dpkg package to enable in 'make menuconfig' options. Now I'm trying to run cross-compiled opencv program on my Rpi but some shared libraries are missing and I want to install these libraries using apt repository (as I already did it on standard Raspbian Stretch os &amp; program run successfully).</p>
  
  <p>I googled it, there's no solution for Buildroot rasbpbian os. Also I tried downloading and installing .deb packages for apt/apt-get/dpkg, didn't work.</p>
  
  <p>apt-get: command not found</p>
  
  <p>I want to cross-compile a kernel which will have all the necessary packages such as apt/dpkg, bin and lib files. Or for the time being to get the work done need guidance to install apt/dpkg packages on Rpi buildroot os.</p>
