From caf0bfa81d1924e84391a1cccbceefa4cc87f880 Mon Sep 17 00:00:00 2001 From: Albrecht Schlosser Date: Fri, 18 Sep 2020 18:07:18 +0200 Subject: Avoid CMake developer warning related to OpenGL/CMP0072 Newer CMake versions warn if CMake policy CMP0072 is not set. We're using "legacy mode" since we use FindOpenGL with `OPENGL_LIBRARIES` and not (yet) the `OpenGL::GL` target.
