webp 1.3 changed the filenames on windows to include a `lib` prefix
(ie libwebp.lib rather than webp.lib) now this is a common thing
on linux and cmake has a `CMAKE_FIND_LIBRARY_PREFIXES` variable that
has a list of prefixes to look for during a `find_library` call.
`CMAKE_FIND_LIBRARY_PREFIXES` gets set during the call to the
`project` method in the main CMakeLists of a project. Now for windows
`lib` is *not* a common prefix by CMake, and it doesn't add "lib" to
CMAKE_FIND_LIBRARY_PREFIXES during that call.
so find library doesn't look for it, the libs are not found and an
unhappy time is had by all. Now the most obvious solution would be to
pass `-DCMAKE_FIND_LIBRARY_PREFIXES=lib` to CMake to sidestep this
however, the `project` call will set the variable overwriting
anything you passed through the CLI.
So the fix here is to have `find_library` counter-intuitively look
for both `libwebp` and `webp`
The last webp update changed the filenames of the webp libraries
on windows causing oiio not to find them and oiio silently build
without webp support, which only came to light after all of
blender was build and a test failed.
This change makes the OIIO validate and error out if certain
dependencies are not found at configure time so these mistakes
are caught early.
zlib's uri is a bit unstable as when they release a new version they
move the last release "elsewhere"
This change switches the upstream URI over to github, which should be
a bit more reliable.
Had put my name here since the choice was between the foundation
and me personally, with the blender authors file now being in
place this can be cleaned up.
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.

request from Thomas, to update the licensing document he needs
a list of all dependencies their versions and their homepage.
for all deps hosted on github the script will do its best to
figure out the landing page, for all others DEPNAME_HOMEPAGE
will have to be set in versions.cmake
To ensure this information is always supplied, the script will
error out with a fatal error informing whoever is working on
the builder to supply this information.

When an offline render was done side by side render preview, further
render preview updates requiring BVH to be rebuilt would trigger a
crash.
This will be fixed upstream the same way in Embree 4.2.

USD has recently renamed their repository from USD to OpenUSD leading
to a change in the URI for this dep and the hash for the previously
released USD 23.05 since the tarball now will have the source in the
OpenUSD-23.05 folder.
Python versions before 3.10 did not have the
`platform.freedesktop_os_release` utils, use the trick based on looking
for distro-specific version files instead as fall-back (same as what was
done in the previous `install_deps.sh` bash script).
This fixes#108487 by applying upstream OIIO commit 8da473e254
This commit fixes the deps builder to include the patch, the actual
bug will not be fixed until the platform maintainers update the OIIO
library in SVN.
Currently on Windows some dependencies are built with MinGW/GCC 3.x
this commit removes that, in favor of building them with MSVC
via msys2. This will make it easier in the future to offer Win/Arm64
builds of blender.
Notable changes:
- This change drops support for the external libxvid library in favor
of ffmpegs built in support for this format. This has been done with
permission from the VFX module.

idiff sometimes locks up while shutting down when the CPU is
oversubscribed. While blender does not rely on the idiff tool
the tests that run on the CI environment do, which causes tests
to occasionally fail due to a timeout.
The root cause is a bit complex but can be found on the oiio tracker
at https://github.com/OpenImageIO/oiio/issues/3851
This change fixes idiff by :
1- Shutting down the thread pool before the main function exits
2- Have the shutdown wait for the pool threads to actually join, to
prevent the OS from forcefully terminating them while they could
potentially still be holding a lock.
This reverts commit 451751380c.
Seems like this broke linux/mac, likely needs to detect of libxvid
is there or not. For now revert until we sort this out.

This is fixed in newer boost versions, but stick to the existing version now
for VFX platform compatibility. This change only affects macOS libraries,
since no other platform uses libc++.
