[Interest] OpenGL — using glDispatchComputeGroupSizeARB

Hi all,

I'm trying to figure out exactly what to include to be able to use the
OpenGL command glDispatchComputeGroupSizeARB (which I'm positive is
supported on my machine/system). Unfortunately, the typical extension
workflow (i.e. #include <QtOpenGLExtensions> in the relevant header file
and QT += openglextensions in the .pro file) does not seem to work — it
still results in an 'use of undeclared identifier' error upon compiling the
code. Any thoughts? I'm on Linux (64bit), using Qt 5.12.
