Thanks Albrecht

Your recipe works fine.

Just for the benefit of anyone else following this;  note that you probably will have to install GLEW, and it's dev package, under Linux or WIN32, to make this work. Some Linux distros may have it installed by default but I think most do not, and WIN32 basically never does.

Without GLEW (or an equivalent GL extension manager) it is "difficult" to access any GL API beyond 2.1 on these hosts.

Note that macOS is a special case here, as "recent" macOS versions expose higher GL APIs "by default" and GLEW is generally not needed there at all. (Indeed, doesn't even work...)
