Where

<arch> - ia32 or intel64

.. note:: Starting with oneTBB 2022.0, 32-bit binaries are supported only by the open-source version of the library.
<lib> - tbb, tbbmalloc, tbbmalloc_proxy or tbbbind
<vcversion>
- 14 - use for dynamic linkage with the Microsoft* C runtime (CRT)
- 14_uwp - use for Windows 10 Universal Windows applications
- 14_uwd - use for Universal Windows Drivers
- _mt - use for static linkage with the CRT
<variant> - _debug or empty
<version> - binary version
<compat_version> - compatibility version for tbbbind

The last column shows, which environment variables are used by the Microsoft* Visual C++* or Intel® oneAPI DPC++/C++ Compiler, to find these subdirectories.

See :ref:Integrate oneTBB <integrate> to learn how to use CMake* and pkg-config tools. To set the environment, see :ref:Next Steps <next_steps>.

.. CAUTION:: Ensure that the relevant product directories are mentioned by the environment variables; otherwise the compiler might not find the required files.

.. note:: Microsoft* C/C++ run-time libraries come in static and dynamic forms. Either can be used with oneTBB. Linking to the oneTBB library is always dynamic.
