A few libraries were updated and a few added.
There are a few depedencies to intel oneAPI which I did not include, since we
refer already to Intel oneAPI already.

A few libraries were updated, a few were added, and a few were missing
from the previous license document.

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.
Includes contributions by Brecht Van Lommel, Ray Molenkamp, Campbell Barton
and Sergey Sharybin.

On Windows/MSVC this gives a minor (~20%) speedup presumably due to a faster float/int formatter. On macOS (Xcode13), this gives a massive speedup, since snprintf that is in system libraries ends up spending almost all the time inside some locale-related mutex lock.
The actual exporter code becomes quite a bit smaller too, since it does not have to do any juggling to support std::string arguments, and the buffer handling code is smaller as well.
Windows (VS2022 release build, Ryzen 5950X 32 threads) timings:
- Blender 3.0 splash scene (2.4GB obj): 4.57s -> 3.86s
- Monkey subdivided level 6 (330MB obj): 1.10s -> 0.99s
macOS (Xcode 13 release build, Apple M1Max) timings:
- Blender 3.0 splash scene (2.4GB obj): 21.03s -> 5.52s
- Monkey subdivided level 6 (330MB obj): 3.28s -> 1.20s
Linux (ThreadRipper 3960X 48 threads) timings:
- Blender 3.0 splash scene (2.4GB obj): 10.10s -> 4.40s
- Monkey subdivided level 6 (330MB obj): 2.16s -> 1.37s
The produced obj/mtl files are identical to before.

This document helps Blender users to known what is the library of each
individual 3rd party components that Blender depend on.
Generated using:

This is based on the libraries in extern and the svn libraries.
For the libraries in extern the README.blender was used as reference.
For the libraries in svn I used `cmake/versions.cmake`.
Note that the crediting is a bit of hit and miss. For some projects this
is very clear, while for others I had to do some digging. Either way I
gave my best shot.
The sources to (re-)generate this file is local at the moment. But it
should be moved to our infra-structure at some point.

Blender actually uses the ICS license, not ISC.
|
|
The license was renamed GPL-license.txt => license/GPL-2.0txt in 0434efa09ddc451.
Although the renaming made all the license files consistent, we are better off
not updating the copyright file in Blender. Instead we can live with some mild
inconsistency in the license names.
|
|
|
|
For the final builds instead of leaving all the license files in the main
folder, we move them to a "license" folder.
Also, adding more licenses here (MIT, Apache, ...).
