CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 3.5 will be removed from a future version of
CMake.
Update the VERSION argument <min> value or use a ...<max> suffix to tell
CMake that the project does not need compatibility with older versions.

CMake Warning (dev) at /usr/share/cmake/Modules/FindOpenGL.cmake:381 (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.

This warning is for project developers. Use -Wno-dev to suppress it.

I have the same compiling error. One could just implement a dummy function, I am just not sure if there is a different underlying problem...
