From ca94946110f4aaeeb0cbc75e11a619b21f295056 Mon Sep 17 00:00:00 2001
From: Max Krummenacher <max.krummenacher@toradex.com>
Date: Thu, 25 Jun 2020 11:27:40 +0000
Subject: [PATCH] configure.ac: don't require eglmesaext.h
E.g. the Vivante EGL implementation does not provide eglmesaext.h.
The commit moves the check for header file existence outside of the
check for existence of a egl packageconfig and makes the existence
of eglmesaext.h optional.
fixes commit fb1acfec ("Fix building against libglvnd-provided EGL headers")
