With the latest libglvnd switch, I suggest adding a USE flag similar to the other projects and the result of that should set the OpenGL_GL_PREFERENCE to suppress the following warning. Don't know if it would solve nor create any new issues, but I have initial success. CMake Warning (dev) at /usr/share/cmake/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/lib64/libGL.so and GLVND libraries for OpenGL and GLX: OPENGL_opengl_LIBRARY: /usr/lib64/libOpenGL.so OPENGL_glx_LIBRARY: /usr/lib64/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:262 (FIND_PACKAGE) This warning is for project developers. Use -Wno-dev to suppress it.
Interesting! Thanks for the heads up.
