CMake Warning (dev) at /usr/share/cmake/Modules/FindOpenGL.cmake:305 (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_PREFERENCE has not been set to "GLVND" or "LEGACY", so for
