System requirements and GL version for build lumahdrv

[pfk-beta]

Hi,

During building lumahdrv I've got following warning:

CMake Warning (dev) at /usr/share/cmake-3.16/Modules/FindOpenGL.cmake:275 (message):
  Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when                                     
  available.  Run "cmake --help-policy CMP0072" for policy details.  Use the                              
  cmake_policy command to set the policy and suppress this warning.                                       

  FindOpenGL found both a legacy GL library:                                                              

    OPENGL_gl_LIBRARY: /usr/lib/x86_64-linux-gnu/libGL.so                                                 

  and GLVND libraries for OpenGL and GLX:                                                                 

    OPENGL_opengl_LIBRARY: /usr/lib/x86_64-linux-gnu/libOpenGL.so                                         
    OPENGL_glx_LIBRARY: /usr/lib/x86_64-linux-gnu/libGLX.so                                               

  OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for                                    
  compatibility with CMake 3.10 and below the legacy GL library will be used.                             
Call Stack (most recent call first):                                                                      
  CMakeLists.txt:20 (find_package)                                   

I have ignored it. But I also get error during compilation:

I have solved problem. Need to install at least following packets: cmake yasm zlib1g-dev libebml-dev libmatroska-dev libpfs-dev libopenexr-dev libgl1-mesa-dev libvpx-dev
