+How to build freeglut on Windows (Visual Studio 2017 or newer)
+--------------------------------------------------------------
+Starting from Visual Studio 2017, VS features built-in
+support for CMake projects:
+https://learn.microsoft.com/cpp/build/cmake-projects-in-visual-studio
+This means that installing CMake separately is not needed.
+
+1. Install the "Desktop development with C++" workload from
+   the VS Installer, which includes CMake and MSVC by default.
+2. Open the project folder from Visual Studio. At this point
+   it will attempt to configure CMake automatically. Once it's done,
+   click on "Open CMake Settings editor" or select
+   "Manage Configurations..." from the build configuration drop-down to
+   make further changes.
+3. After adjusting the CMake options (or just using the default
+   configuration), click on "Build > Build All". By default, this will
+   generate output in the "out" subdirectory of your project. A list of
+   available options is given below.
