Wayland EGL External Platform library

=====================================

Overview

--------

This is a work-in-progress implementation of a EGL External Platform library to

add client-side Wayland support to EGL on top of EGLDevice and EGLStream

families of extensions.

This library implements an EGL External Platform interface to work along with

EGL drivers that support the external platform mechanism. More information

about EGL External platforms and the interface can be found at:

https://github.com/NVIDIA/eglexternalplatform

Building and Installing the library

-----------------------------------

This library build-depends on:

 * EGL headers

       https://www.khronos.org/registry/EGL/

 * Wayland libraries & protocols

       https://wayland.freedesktop.org/

 * EGL External Platform interface

       https://github.com/NVIDIA/eglexternalplatform

To build, run:

    ./autogen.sh

    make

To install, run:

    make install

You can also use meson build system to build and install:

    meson builddir

    cd builddir

    ninja

    ninja install

*Notes*:

The NVIDIA EGL driver uses a JSON-based loader to load all EGL External

platforms available on the system.

If this library is not installed as part of a NVIDIA driver installation,

a JSON configuration file must be manually added in order to make the

library work with the NVIDIA driver.

The default EGL External platform JSON configuration directory is:

  `/usr/share/egl/egl_external_platform.d/`

platform.
