-- Boost version: 1.68.0
-- Found the following Boost libraries:
-- unit_test_framework
-- regex
-- system
CMake Warning (dev) at /usr/share/cmake-3.12/Modules/FindOpenGL.cmake:270 (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/libGL.so

  and GLVND libraries for OpenGL and GLX:

    OPENGL_opengl_LIBRARY: /usr/lib/libOpenGL.so
    OPENGL_glx_LIBRARY: /usr/lib/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:61 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
