MoltenVK original intent was to let developers work on a mac system developing
for the vulkan eco-system. MoltenVK doesn't support all the features that we
require and would require additional workarounds to be actually supported.
It is not expected that we will release Blender with MoltenVK for this reason.
But it still has value for shader developers to validate shaders on metal and
vulkan on a single platform.

This change fixes confusion situation when the render output
is an RGBA image: the difference in color was not visible in
the report because alpha channel was all zeros. This is due
to idiff performing per-channel difference.
The solution to this problem is to have separate images for
color and alpha difference, which makes it clear where the
difference actually is coming from.
Harfbuzz and FriBiDi are included in our external libraries for all
platforms. This PR adds the glue to make them available as optional
build components (off by default).

Previously the cmake code would try to run the LIBDIR specific "findX.cmake" files for both vulkan and shaderc.
However these would pick up system headers and libraries when LIBDIR were not present. This would lead to compilation errors as the system library configurations were not taken into account or queried.
This changes it so that if LIBDIR is not present, the proper pkgconfig files will be used instead.

The official SDK was released, add correct paths for that version. The
old paths can be removed once the buildbot uses this SDK.
The SDK installer sets a HIP_PATH environment variable. This is used to
automatically detect the location when HIP_ROOT_DIR is not manually
specified.

Changes in 42713bf made it ignore the environment variable if there is a
defined but empty CMake variable. Also make similar changes for other
GPU compute APIs, to guard against future problems like this.

The sound equalizer is using the Audaspace FFT Convolver.
The blender part creates an array of descriptions of power per "band"
and orders the creation of Equalizer (ISound) in the Audaspace.
Modifier can be created on sound strips. It lets you define
amplification or attenuation over frequency range from 30Hz to 20 kHz.
The power is limited to -30 db - 30 db. This is done using curve
mapping widget.

The error message was written assuming the default version was set,
making the error confusing.
Adjust the error message when the non-default version is missing.
The `Find*.cmake` modules originally used uppercase commands to match
CMake's own conventions. Since then CMake uses lower-case and even
within our own find modules, using all uppercase wasn't done
consistently. Opt for lowercase everywhere.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
This is the minimal change required to start using modern CMake in the
blender build system. This change is designed to allow small
incremental changes to the build system rather than doing it in one
big bang which would be unmaintainable (for me)
The biggest functional change is, previously all libraries in the
`LIB` section of a `blender_add_lib` call had the `INTERFACE` scope,
which is rarely, if ever the correct scope. This diff changes this to
`PRIVATE`
Concrete implications of this diff :
The `LIB`, `INC` and `INC_SYS` sections of an `blender_add_lib` call
now allow scoping keywords (`PUBLIC`, `PRIVATE,` `INTERFACE`) to
declare the scope of the dependency.
Right now the only library using any modern cmake is
`bf_intern_atomic` which is an header only interface library that will
just advertise its include directories.
This allows us to clean up any `CMakeLists.txt` that adds
`../../../intern/atomic` to its `INC` section to remove it in `INC` by
adding a `PRIVATE bf_intern_atomic` to the `LIB` section.

Upgrade to the latest SDK, and enable in daily and release builds where it's
available as an option under Preferences > System.
There are some known limitations, see #104110 and release notes.

When Python is not found, inform developers how they can use a newer
version. Even though it's not officially supported - we typically keep
the latest stable version of Python working.
* Add HIP-RT API functions and library loading
* Add more HIP API types and functions
* Find HIP linker executable in CMake module
* New CMake module to find HIP-RT SDK

Using the new HIP SDK 5.5 that includes a fix for the compiler bug.
This also enables the light tree.
For Linux the binaries are still disabled. ROCm 5.5 is planned to
include the same fix but not released yet. When that happens we
should be able to enable Linux as well.

OpenEXR has some dependecies that other other modules in Blender
requires. When disabling OpenEXR these dependecies could not match
and building blender would fail.
This PR disables the next options when `WITH_IMAGE_OPENEXR=Off`
- `WITH_OPENVDB`
- `WITH_ALEMBIC`
- `WITH_VULKAN_BACKEND`
- `WITH_CYCLES_OSL`
Additionally windows stores the IMath libraries in `IMATH_LIBRARIES`
Linux and Mac stored the IMath libraries in `IMATH_LIBRARY`. This
change will also adds `IMATH_LIBRARIES` variable to all platforms.

Paths to vulkan libraries, paths and related components were
hardcoded in the platform cmake file. This patch separates
this by using adding CMake modules for Vulkan and ShaderC.
This change has only been applied to the macOs configuration as
that is currently our main platform for development. Other platforms
will be added during the development of the Vulkan back-end.
MoltenVK wasn't found as it was previous part of lib/vulkan.
as lib/vulkan now doesn't contain
the full sdk, we will use a moltenvk folder.
At this moment the moltenvk folder isn't filled, but will eventually be.
This makes it convenient to build blender without referencing
pre-compiled libraries which don't always work on newer Linux systems.
Previously I had to rename ../lib while creating the CMakeCache.txt
to ensure my systems libraries would be used.
This change ensures LIBDIR is undefined when WITH_LIBS_PRECOMPILED is
disabled, so any accidental use warns with CMake's `--warn-unused-vars`
argument is given.
