This checkin will use OIIO to replace the image save/load code for BMP,
DDS, DPX, HDR, PNG, TGA, and TIFF.
This simplifies our build environment, reduces binary duplication,
removes large amounts of hard to maintain code, and fixes some bugs
along the way.
It should also help reduce rare differences between Blender and Cycles
which already uses OIIO for most situations. Or potentially makes them
easier to solve once discovered.

When using ASAN on Clang / Linux, the call to `find_library(... asan ...)`
works against us, as it finds GCC's `libasan.so`. To work with Clang,
we should simply not pass any explicit library, as Clang will figure things
out by itself with the `-fsanitize=xxx` options.
Furthermore, Clang is incompatible with `-fsanitize=object-size`, so that's
now also no longer passed on Linux (mimicking the Apple) configuration.
For the long run, it would be better to rewrite this entire section to
select behaviour on a per-compiler basis, rather than per platform. That's
tracked in #105956

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.

The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
This PR uses renderdoc for frame capturing when enabled.
It enabled an easier workflow for frame capturing.
- Capture GPU API calls from test cases
- Capture GPU API calls from background threads
- Capture GPU API calls from background rendering.
Renderdoc is an important GPU debugger used by the Eevee/
Viewport module. Previously we needed to change code in
order to record background rendering, that could on its own
lead to other side-effects.
The integration with renderdoc can be enabled using
`WITH_RENDERDOC=On` compiler option. `GPU_debug_capture_begin`
and `GPU_debug_capture_end` can be added to the section
of the code you want to debug. When running Blender inside
renderdoc this part will automatically be captured.
All GPU test cases are now guarded by these calls. In order
to capture the test cases you need to start the test cases
from renderdoc and the captured GPU API calls will appear
where each capture is a single test case.

The C4100 warning is related to unused formal parameters in functions.
Enabling it better aligns with "-Wunused-parameter" option in other
compilers.
While suppressing it with `__pragma(warning(suppress:4100))` is not the
same as using `__attribute__((__unused__))` in GCC or Clang, it is
still preferable to use it over completely hiding the warning.
This ensures consistent warning behavior across compilers and improves
code quality by addressing unused function parameters.
(Note that some warnings in Windows-specific code have already been
silenced in 7fcb262dfd2f48a73f9cf794944ff677c36e3783)

New (experimental) Stanford PLY importer and exporter written in C++.
Handles: vertices, faces, edges, vertex colors, normals, UVs. Both
binary and ASCII formats are supported.
Usually 10-20x faster than the existing Python based PLY
importer/exporter.
Additional notes compared to the previous Python addon:
- Importing point clouds with vertex colors now works
- Importing PLY files with non standard line endings
- Exporting multiple objects (previous exporter didn't take the vertex
indices into account)
- The importer has the option to merge vertices
- The exporter supports exporting loose edges and vertices along with
UV map data

During the discussion for #101413 there was consensus that we could make
OIIO a mandatory dependency. This patch does just that.
The `idiff` testing tool remains optional.
Pull Request #105111
This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).
Pull Request #104755
This better aligns with OSX/Linux warnings.
Although `__pragma(warning(suppress:4100))` is not the same as
`__attribute__((__unused__))` in gcc (which only affects the attribute
instead of the line), it still seems to be better to use it than to
hide the warning entirely.
The internal compiler error appears to be gone. Unclear why it appeared in the
first place and why it's gone now. Just random kernel code changes causing it.
Pull Request #104719
Vulkan has a pluggable memory allocation feature, which allows internal
driver allocations to be done by the client application provided
allocator. Vulkan uses this for more client application allocations
done inside the driver, but can also do it for more internal oriented
allocations.
VK_ALLOCATION_CALLBACKS initializes allocation callbacks for host allocations.
The macro creates a local static variable with the name vk_allocation_callbacks
that can be passed to vulkan API functions that expect
const VkAllocationCallbacks *pAllocator.
When WITH_VULKAN_GUARDEDALLOC=Off the memory allocation implemented
in the vulkan device driver is used for both internal and application
oriented memory operations.
For now this would help during the development of Vulkan backend to
detect hidden memory leaks that are hidden inside the driver part
of the stack. In a later stage we need to measure the overhead and
if this should become the default behavior.
Pull Request #104434
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.
These warnings can reveal errors in logic, so quiet them by checking
if the features are enabled before using variables or by assigning
empty strings in some cases.
- Check CMAKE_THREAD_LIBS_INIT is set before use as CMake docs
note that this may be left unset if it's not needed.
- Remove BOOST/OPENVDB/VULKAN references when disable.
- Define INC_SYS even when empty.
- Remove PNG_INC from freetype (not defined anywhere).
As noted in comments, there are a lot of false positives which can't
be conveniently suppressed. Many of these warnings were caused by
`float x, y, z` being passed as `float[3]` using a pointer to `x`.
A few weeks ago we enabled the Metal back-end for the viewport.
Due to metal, master is only able to build on MacOS 10.15 and above.
The previous minimum requirement is MacOS 10.13.
It was already planned to bump to a higher version for Blender 3.6. After
a short discussion via bf-committers it was decided that it is fine to bump it for
3.5 release.
This patch cleans up the CMake files and update the minimum requirement.
With this patch the next deprecations will be listsed.
- `NSOpenGLView`, `NSOpenGLContext` is deprecated. (replaced by metal)
- `NSStringPboardType` is replaced by `NSPasteboardTypeString`
- `NSTIFFPboardType` is replaced by `NSPasteboardTypeTIFF`
- `NSFilenamesPboardType` should be replaved by multiple pasteboard items with `NSPasteboardTypeFileURL` instead.
- `NSUserNotification` should be replaced with UserNotifications.frameworks API
Deprecations will be handled in separate tasks and commits. OpenGL won't be
fixed at this moment, as it will be phased out in the future. NSStringPboardType, NSTiffPboardType & NSFilenamesPboardType
will be provided in a single patch. NSUserNotification will also be provided in
its own patch.

To aid in debugging the case where your compiler is too old for Blender,
actually log which version CMake found.
Before, CMake would output:
```
CMake Error at CMakeLists.txt:121 (message):
The minimum supported version of GCC is 11.0.0
```
With the patch, it logs:
```
CMake Error at CMakeLists.txt:121 (message):
The minimum supported version of GCC is 11.0.0, found 10.4.0
```
This has been implemented for GCC and Clang. MSVC has been explicitly
excluded, as the version numbers used for this comparison are internal
versions and not directly usable/recognisable.

This is now only an indirect dependency on shared libraries, which means
this combination is valid.
Also remove mechanism that automatically disabled WITH_BOOST if no libraries
are using it, this is no longer really helpful with shared boost libraries.
There are dependencies between shared libraries, and Python modules which are
always installed on Linux and macOS can use these also.
Instead of adding logic for dealing with dependencies and conditional Python
module installs, just always install everything when using precompiled
libraries. This does not affect compile time which would be the main reason to
turn off build options, and it does not affect the case where system libraries
are used.
More automatic and convenient to update existing configurations this way.
Also move into platform_old_libs_update.cmake where similar logic was put
already.
This functionality is related only to debugging of SYCL implementation
via single-threaded CPU execution and is disabled by default.
Host device has been deprecated in SYCL 2020 spec and we removed it
in 305b92e05f748a0fd9cb62b9829791d717ba2d57.
Since this is still very useful for debugging, we're restoring a
similar functionality here through SYCL 2020 Host Task.
This enable building the metal backend by default on Apple hardware.
This is needed for further testing and the new backend selector D16774.

MoltenVK is part of the vulkan SDK. Blender requires the vulkan SDK
to compile. This patch adds the MoltenVK includes and libraries to
the Vulkan includes and libraries.
This adds a vulkan backend to GHOST. The code was extracted from the
tmp-vulkan branch. The main difference with the original code is that
GHOST isn't responsible for fallback. For Metal backend there is already
an idea that the GPU module is responsible for the fallback, not the system.
For Blender we target Vulkan 1.2 at the time of this patch.
MoltenVK (needed to convert Vulkan calls to Metal) has been added as
a separate package.
This patch isn't useful for end-users, currently when starting blender with
`--gpu-backend vulkan` it would crash as the `VBBackend` doesn't initialize
the expected global structs in the GPU module.
Validated to be working on Windows and Apple. Linux still needs to be tested.

This was previously needed due to poor compatibility between Visual Studio and
NVCC. But it has not been used for a while now as compatibility seems to have
improved.
Jack has not been installed on the buildbot builders for a long time and so
should not be enabled by default to pass strict build options added in D16104.
However for those doing custom builds the option should remain available.
Creating `__pycache__` directories in SVN's lib/ directory can cause
updating SVN to fail. Add the -B flag when TEST_PYTHON_EXE from LIBDIR
is used so so Python doesn't generate this cache.
This patch adds a placeholder for the vulkan backend.
When activated (`WITH_VULKAN_BACKEND=On` and `--gpu-backend vulkan`)
it might open a blender screen, but nothing should be visible as
none of the functions are implemented or otherwise crash on a nullptr.
This is expected as this is just a placeholder. The goal is to add shader compilation
+validation to this backend as one of the next steps so we can validate
changes to existing shaders on OpenGL, Metal and Vulkan at the same time.

This is to help ensure buildbot builds are correct, while still gracefully
disabling features in user/developer builds.
* Add WITH_STRICT_BUILD_OPTIONS to give an error when features can't be
enabled due to missing libraries or other reasons. Add new macro
set_and_warn_library_found used everywhere features were being
automatically disabled.
* Remove code from Windows and macOS for various libraries that would
automatically disable features. set_and_warn_library_found could be
used here also, but we are generally assuming the precompiled libraries
are complete and only test for availability when libraries are just
added.

It has not actually been enabled there for a long time in official releases,
so this just fixes the warning. Making it work again would be good, but for
now JACK is only supported on Linux.
