The location of the shaders changed with OSL 1.11.10. This commit is therefore in addition to D10212.
@sybren With the latest SVN libraries, I am fairly certain there is a "OSL not found" in the CMake output. Can you check on Linux?
@LazyDodo Since you haven't pushed the new OSL libs yet, this should not be a problem on Windows. So this will only be needed whenever those land.

This bumps OSL to 1.11.10.0. OSL Has a new build time
dependency: Clang, and more importantly it expects
clang and llvm to share a library folder, which it
previously for us did not.
This patch changes:
-OSL Update to 1.11.10.0
-refactor the llvm/clang/clang-tools-extra builds into the llvm
build using the llvm-project tarball for building that has all
of the subprojects in it.
-update ispc/openmp builds since clang no longer its own dependency
and they have to depend on the llvm build now.
-Update the windows builder to use the 64 bit host tools since it
ran out of ram linking clang
-Since OSL now needs clang to link successfully a findclang.cmake
has been provided for linux/OSX

This updates platform/platform_win32.cmake to support
both the old and new library names for OpenXR.
The new version links against one additional system
library and the debug library filename changed ever
so slightly.
This is a temporary workaround and can be removed
once the new lib versions have landed.
Rather than hardcoding the lib names, read
boosts version.hpp and extract the version
from there.
This will make it easier to land lib changes
in the near future.
* WITH_CPU_SSE was renamed to WITH_CPU_SIMD, and now covers both SSE and Neon.
* For macOS sse2neon.h is included as part of the precompiled libraries.
* For Linux it is enabled if the sse2neon.h header file is detected. However
this library does not have official releases and is not shipped with any Linux
distribution, so manual installation and configuration is required to get this
working.
Ref D8237, T78710
This required using a fork of Embree, newer LLVM version, unreleased ISPC
version and sse2neon directly from Git. Hopefully over time all the required
changes end up in official releases. For now we deviate from other platforms.

Build System
============
This is an API breaking new version, and the updated code only builds with
OpenColorIO 2.0 and later. Adding backwards compatibility was too complicated.
* Tinyxml was replaced with Expat, adding a new dependency.
* Yaml-cpp is now built as a dependency on Unix, as was already done on Windows.
* Removed currently unused LCMS code.
* Pystring remains built as part of OCIO itself, since it has no good build system.
* Linux and macOS check for the OpenColorIO verison, and disable it if too old.
Ref D10270
Processors and Transforms
=========================
CPU processors now need to be created to do CPU processing. These are cached
internally, but the cache lookup is not fast enough to execute per pixel or
texture sample, so for performance these are now also exposed in the C API.
The C API for transforms will no longer be needed afer all changes, so remove
it to simplify the API and fallback implementation.
Ref D10271
Display Transforms
==================
Needs a bit more manual work constructing the transform. LegacyViewingPipeline
could also have been used, but isn't really any simpler and since it's legacy
we better not rely on it.
We moved more logic into the opencolorio module, to simplify the API. There is
no need to wrap a dozen functions just to be able to do this in C rather than C++.
It's also tightly coupled to the GPU shader logic, and so should be in the same
module.
Ref D10271
GPU Display Shader
==================
To avoid baking exposure and gamma into the GLSL shader and requiring slow
recompiles when tweaking, we manually apply them in the shader. This leads
to some logic duplicaton between the CPU and GPU display processor, but it
seems unavoidable.
Caching was also changed. Previously this was done both on the imbuf and
opencolorio module levels. Now it's all done in the opencolorio module by
simply matching color space names. We no longer use cacheIDs from OpenColorIO
since computing them is expensive, and they are unlikely to match now that
more is baked into the shader code.
Shaders can now use multiple 2D textures, 3D textures and uniforms, rather
than a single 3D texture. So allocating and binding those adds some code.
Color space conversions for blending with overlays is now hardcoded in the
shader. This was using harcoded numbers anyway, if this every becomes a
general OpenColorIO transform it can be changed, but for now there is no
point to add code complexity.
Ref D10273
CIE XYZ
=======
We need standard CIE XYZ values for rendering effects like blackbody emission.
The relation to the scene linear role is based on OpenColorIO configuration.
In OpenColorIO 2.0 configs roles can no longer have the same name as color
spaces, which means our XYZ role and colorspace in the configuration give an
error.
Instead use the new standard aces_interchange role, which relates scene linear
to a known scene referred color space. Compatibility with the old XYZ role is
preserved, if the configuration file has no conflicting names.
Also includes a non-functional change to the configuraton file to use an
XYZ-to-ACES matrix instead of REC709-to-ACES, makes debugging a little easier
since the matrix is the same one we have in the code now and that is also
found easily in the ACES specs.

Standard wiki build instructions for building Blender on macOS can now be used
on Macs with ARM processors.
This contains all libraries except for Embree and OpenImageDenoise, so Cycles
performance does not yet have full performance and features in this build. An
x86-64 build is likely to still render faster than arm64 until Embree is added.
Uses the new lib/darwin_arm64 folder. For simplicity and to keep download size
under control, both for end users and builders, we are not planning to ship
universal binaries. So this is a separate folder from lib/darwin.

When building with more aggressive optimization flags, GCC will add FMA
(Fused Multiply Add) instructions that will slightly alter the floating
point operation results.
This causes some automated tests to fail in blender.
In clang and the intel compiler ffp-contract is set to off per default

This commit expands the Windows-specific code in rBdca9aa0053f7 and Linux-specific code in rB33b7d53df08a.
It also fixes a capitalization issue in FindPugiXML.cmake
PugiXML was historically shipped hidden embedded into OIIO, the Grease
Pencil team had a requirement for an XML library recently so pugi seems
like a natural choice since it's not really a 'new' library, we just
turn an implicit dependency into an explicit one.
This commit expands the Windows-specific code in rBdca9aa0053f7 to
include Linux. macOS support will be handled in a later commit.
NOTE: run `cmake -U'*PUGIXML*' .` in the build directory to ensure CMake
finds PugiXML in the new location.
For details see D8628
This separates out PugiXML that was previously
bundled by OIIO.
As this linux/mac libs are not available
this commit only contains the builder and windows
changes, and the option to enable pugixml is
guarded by a platform if, this can be removed
once all platforms have committed the svn libs.

Cmake must never look into Frameworks when the system
library guards (`without_system_libs_begin`/`without_system_libs_end`)
are present.
OpenAL didn't follow this and OpenAL.framework in Xcode would be used.
The Cmake's `FindOpenAL.cmake` looks for both library (in this case,
the .framework file), and include dir.
Precompiled libraries don't contain the former. So `find_package`
cannot be used, or it becomes the hack that {rBb2c707747da9} removed.
So hardcode the include dir path, and other variables.

For multi-config generators, tests are in `bin/tests/<config>` folder.
and OpenMP cannot be found at `@executable_path/../Resources/lib`.
So create that folder and put the library there to be used by tests.
It is not ideal to copy the library around. When minimum CMake version

Came across this due to the custom built LLVM toolchain I'm using.
After tests were bundled in a single executable and cycles and libmv
created their own tests, the warnings on macOS have gone over 800.
The reason is setting `*_LIBRARIES` to names of the libraries
and later using `link_directories` to link them properly.

Warnings like the following popup for every target/executable,
for every library it links to.
```
ld: warning: directory not found for option
'-L/Users/me/blender-build/blender/../lib/darwin/jpeg/lib/Debug'
```
The patch completes a step towards removing `link_directories` as
mentioned in TODO at several places.
The patch uses absolute paths to link libraries and removes
all `*_LIBPATH`s except `PYTHON_LIBPATH` from
`platform_apple.cmake` file. (The corner case where it's used seems
like dead code. Python is no longer shipped with that file structure.)
Also, unused code for LLVM-3.4 has been removed.
Also, guards to avoid searching libraries in system directories have
been added.
`APPLE` platform now no longer needs `setup_libdirs`,
`cycles_link_directories`, and `link_directories`.
The number of warnings now is less than 100, most of them being
deprecation ones in dependencies.

NanoVDB is a platform-independent sparse volume data structure that makes it possible to
use OpenVDB volumes on the GPU. This patch uses it for volume rendering in Cycles,

Since it has a big impact on memory usage and performance and changes the OpenVDB

itself with the "WITH_NANOVDB" CMake option.

This reverts commit 5eb5978043.
The change was problematic:
*Advanced users may prefer managing schemes manually and adding only
a few that they need, instead of one for every library/executable
Blender builds.
*If CMake creates schema files, it overwrites the changes a developer
made every time CMake is run. If Xcode creates scheme files, it keeps
settings/ environment variables intact.
If someone runs CMake very frequently, pass
`-DCMAKE_XCODE_GENERATE_SCHEME=ON` to `cmake` while configuring.
