With cmake 3.16, I get the 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:227 (FIND_PACKAGE)
This warning is for project developers. Use -Wno-dev to suppress it.

What about the attached patch?
The resulting hugin executable works fine here.
