Use GLVND also when legacy implementations exist for old cmake versions
<= 3.10. This is a breaking change for old cmake versions (prior to
around 2017-10-05) which will now use GLVND rather than defaulting to
libGL.
This fixes the following warning when building:
CMake Warning (dev) at /gnu/store/qv13zgbmyx0vjav8iiqp772kp6rxvwnd-cmake-3.24.2/share/cmake-3.24/Modules/FindOpenGL.cmake:315 (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: /home/simendsjo/.guix-profile/lib/libGL.so
and GLVND libraries for OpenGL and GLX:
OPENGL_opengl_LIBRARY: /home/simendsjo/.guix-profile/lib/libOpenGL.so
OPENGL_glx_LIBRARY: /home/simendsjo/.guix-profile/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):
cmake/LibraryConfigurations.cmake:21 (find_package)
src/CMakeLists.txt:46 (include)
This warning is for project developers. Use -Wno-dev to suppress it.
