Recent change in [0] caused the CFLAGS variables not to be manipulated
by remove_cc_flag. Unfortunately EVAL is needed to set a variable
that references a variable name.

Many calls to add_check_c_compiler_flag add_check_cxx_compiler_flag
resulted in over long lines & visual noise. Replace with a function that
takes multiple (cache_var flag) pairs to reduce duplication.
Hydra is a rendering architecture part of USD, designed to abstract the
host application from the renderer. A renderer implementing a Hydra
render delegate can run in any host application supporting Hydra, which
now includes Blender.
For external renderers this means less code to be written, and improved
performance due to a using a C++ API instead of a Python API.
Add-ons need to subclass bpy.types.HydraRenderEngine. See the example in
the Python API docs for details.
An add-on for Hydra Storm will be included as well. This is USD's
rasterizing renderer, used in other applications like usdview. For users
it can provide a preview of USD file export, and for developers it
serves a reference.
There are still limitations and missing features, especially around
materials. The remaining to do items are tracked in #110765.
This feature was contributed by AMD.

- Fix using forward declarations when extracting struct information as
it causing this check to be ignored.
- Fix extracting comments which sometimes included code fragments.
- Fix extracting the outer comment for struct declarations on a single
line.
- Skip source files in the build directory.
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.

This utility uses Python's clang module to validate comments intended
to match the struct member names. `cmake_static_check_clang.py` has
been written to support adding other checkers in the future.
`list_assert_duplicates` validates a list that should contain no
duplicates, contains no duplicates, with scope keywords now being
allowed in `INC` sections, there is the situation where multiple
include paths can have the same scope set on them causing
`list_assert_duplicates` to error out.
To remedy this we remove the scope keywords from the list first,
before running the test.
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.
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.

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).
When using the `WITH_LINKER_LLD` option, the logic to find the `ld.lld`
binary and actually tell the build system to use it was specific to GCC.
I've copied the Clang-specific logic for Mold and adjusted it to find
LLD.
Not entirely sure why this is necessary, as LLD is actually Clang's
linker. However, without this change, CMake would use regular old slow
`ld` to link.
