So I had to use libglvnd from git master to get this working with <EGL/eglext.h> I'm not sure how this is supposed to work on machines that use the old headers - I've asekd the question on the merge request
Git commit 2c76cc4784382b3df9b5413860d0793ea26cea31 by Vlad Zahorodnii. Committed on 29/05/2020 at 13:21. Pushed by vladz into branch 'Plasma/5.18'. [wayland] Fix misuse of EGL/eglmesaext.h The recommended way to get all EGL extension defines is to include EGL/eglext.h. EGL/eglmesaext.h is a private header that compositors should not use.
