[anari] Added ANARI port.

[acdemiralp]

• Changes comply with the maintainer guide
• The name of the port matches an existing name for this component on https://repology.org/ if possible, and/or is strongly associated with that component on search engines.
• Optional dependencies are resolved in exactly one way. For example, if the component is built with CMake, all find_package calls are REQUIRED, are satisfied by vcpkg.json's declared dependencies, or disabled with CMAKE_DISABLE_FIND_PACKAGE_Xxx
• The versioning scheme in vcpkg.json matches what upstream says.
• The license declaration in vcpkg.json matches what upstream says.
• The installed as the "copyright" file matches what upstream says.
• The source code of the component installed comes from an authoritative source.
• The generated "usage text" is accurate. See adding-usage for context.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is in the new port's versions file.
• Only one version is added to each modified port's versions file.

You should run vcpkg x-add-version anari to add the versions file.

I am looking into the CI failures. I locally tested x86-windows and x64-windows and they seem to work.

Edit: The CI seems to fail on line find_package(Python3 REQUIRED COMPONENTS Interpreter) on Windows.

Edit: The only remaining error is:

C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.37.32822\include\immintrin.h(15): fatal error C1189: #error:  This header is specific to X86, X64, ARM64, and ARM64EC targets

This occurs in ARM64 debug mode, release works fine. I am looking for a solution.

Edit: The error is due to MSVC or Embree. Disabling port on ARM64 Windows until it is fixed.

Also, is it OK for the default implementation library (anari::helide) to depend on an internally downloaded version of Embree? Look at https://github.com/KhronosGroup/ANARI-SDK/blob/main/libs/helide/external/embree/CMakeLists.txt to see where this happens. I believe this is an intentional decision by Khronos; to have one "safe" device that works anywhere and does not depend on anything. If not, it is possible to disable it via -DBUILD_HELIDE_DEVICE=OFF in vcpkg_cmake_configure.

I think its good to go. Checked the installation directories as a last step, everything looks clean.

Please add the failed triplet to the ci. baseline instead of the supports field.

Usage tested pass on x64-windows.
No feature needs to test.

Looks like this port is being a bad kitty and trying to recursively download inside the build.

Also it's a bit scary that this isn't using the embree port

I am looking into this now. The fastest way out is to disable the Helide implementation with -DBUILD_HELIDE_DEVICE=OFF. The better way is to patch the cmake to use the vcpkg Embree. I'll probably do the latter and open an MR.

Edit: Currently, the only real solution is -DBUILD_HELIDE_DEVICE=OFF. Helide depends on the https://github.com/embree/embree/tree/master/common directory of Embree which is not packaged with the Embree3 port. Please see MR #33616 .
