  $ sudo apt install libavcodec-dev libavformat-dev libswscale-dev libavresample-dev
  $ sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
  $ sudo apt install libxvidcore-dev x264 libx264-dev libfaac-dev libmp3lame-dev libtheora-dev
  $ sudo apt install libfaac-dev libmp3lame-dev libvorbis-dev
  
  

• (Optional) OpenCore - Adaptive Multi Rate Narrow Band (AMRNB) and Wide Band (AMRWB) speech codec

  $ sudo apt install libopencore-amrnb-dev libopencore-amrwb-dev
  
  

• Cameras programming interface libs

  $ sudo apt-get install libdc1394-22 libdc1394-22-dev libxine2-dev libv4l-dev v4l-utils
  $ cd /usr/include/linux
  $ sudo ln -s -f ../libv4l1-videodev.h videodev.h
  $ cd ~
  

• GTK lib for the graphical user functionalites coming from OpenCV highghui module

   sudo apt-get install libgtk-3-dev
  

• Python libraries for python3:

  $ sudo apt-get install python3-dev python3-pip
  $ sudo -H pip3 install -U pip numpy
  $ sudo apt install python3-testresources
  

• Parallelism library C++ for CPU

  $ sudo apt-get install libtbb-dev
  

• Optimization libraries for OpenCV

  $ sudo apt-get install libatlas-base-dev gfortran
  

• Optional libraries:

  sudo apt-get install autoconf automake libtool curl make g++ unzip
  
  wget <https://github.com/protocolbuffers/protobuf/releases/download/v3.6.1/protobuf-all-3.6.1.tar.gz>
  
  tar -xzvf protobuf-all-3.6.1.tar.gz
  
  cd protobuf-3.6.1
  
  ./configure
  make
  sudo make install
  sudo ldconfig  # Bu komut, paylaşılan kitaplık bağlantılarını yeniler.
  
  protobuf yukaridaki gibi kurulduysa bu satıra gerek yok.
  $ sudo apt-get install libprotobuf-dev protobuf-compiler
  
  $ sudo apt-get install libgoogle-glog-dev libgflags-dev
  $ sudo apt-get install libgphoto2-dev libeigen3-dev libhdf5-dev doxygen
  

We will now proceed with the installation (see the Qt flag that is disabled to do not have conflicts with Qt5.0).
