Notes on specific projects

...

Info

Only OneTBB as specified in the 2025 standard works. TBB 2020.3 as defined in older versions does not work without a large patch - an example can be seen in Blender (this has since been removed, as Blender now follows the 2025 spec): https://projects.blender.org/blender/blender/src/branchcommit/maind5823ad8959abe611fd4dac8125ed0921dbf7276/build_files/build_environment/patches/tbb.diff

Note that things such as TBBmalloc do not work with the Blender patch, and would require further engineering effort to enable

Code Block
git clone https://github.com/AcademySoftwareFoundation/OpenColorIO
cd OpenColorIO
mkdir build
cd build
cmake .. -G"Ninja" -DCMAKE_BUILD_TYPE=Release
cmake --build . --config Release

OpenImageIO

OpenImageIO is also an adjacent program, and has a large number of dependencies - luckily it can build them by itself:

Code Block
git clone https://github.com/AcademySoftwareFoundation/OpenImageIO
cd OpenImageIO
mkdir build
cd build
cmake .. -G"Ninja" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=<OIIO install dir> -DOpenImageIO_BUILD_MISSING_DEPS=all -Dminizip-ng_INCLUDE_DIR=%CD%\deps\dist\include\minizip-ng -DBUILD_SHARED_LIBS=OFF
cmake --build . --config Release
Info

Line 5 might need to be run twice, as the first attempt may end in an unknown failure - it should still build though

OSL (Open Shader Language)

OSL is another adjacent project to the VFX reference platform - build instructions are not included here, as they require building your own copy of LLVM. An example of how it can be build can be seen as part of the Blender build files: https://projects.blender.org/blender/blender/src/branch/main/build_files/build_environment/cmake/osl.cmake
