Hello,
can anyone guide me how to build VTK with VTK\_SMP\_IMPLEMENTATION\_TYPE = TBB on Windows?
I downloaded TBB from [https://github.com/intel/tbb/releases](https://github.com/intel/tbb/releases).
[tbb-2020.1-win.zip](https://github.com/intel/tbb/releases/download/v2020.1/tbb-2020.1-win.zip)
Unfortunately, I don’t know which folders have to be set since there are various possibilities (e.g. tbb/bin/intel64/vc14 or tbb/bin/intel64/vc14 etc.).
I tried to set all “INCLUDE\_DIR” to “tbb\include” all “LIBRARY” DIRs to “tbb\lib\intel64\vc14” but I received some TBB related build errors.
Moreover there is a QGLWidget related error which also occurs when building without TBB.
Thank you for your help.

Most applications nowadays depend on a number of third-party libraries, which are downloaded/built automatically using CMake External Project infrastructure.
In your project, you would dowbload TBB and pass its path to VTK. See an example here: [https://github.com/Slicer/Slicer/blob/master/SuperBuild/External\_VTK.cmake](https://github.com/Slicer/Slicer/blob/master/SuperBuild/External_VTK.cmake)

FYI, you can build with OpenMP easilly as it is integrated in visual studio.

If you need to configure TBB manually, you can do that by:
VTK\_SMP\_IMPLEMENTATION\_TYPE: VTK
TBB\_INCLUDE\_DIR: Path to the folder which contains tbb/tbb.h
TBB\_LIBRARY\_DEBUG: (Path)/tbb\_debug.lib
TBB\_LIBRARY\_RELEASE: (Path)/tbb.lib
Also, make sure to always use forward slashes with cmake paths.

I have built VTK with TBB on macOS, linux, and iOS. Still need to get around to Android. (We don’t use windows sorry)
Here’s my configure command:
```bash
export TBB_ROOT=$PATH_TO_TBB//tbb_2019-linux/
cmake \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=$PWD/install \
-DBUILD_EXAMPLES=OFF \
-DBUILD_TESTING=OFF \
-DVTK_SMP_IMPLEMENTATION_TYPE=TBB \
../vtk
```
You might have to configure the `FindTBB.cmake` to not use the CMAKE\_FIND\_ROOT\_PATH like I did for iOS: [https://gitlab.kitware.com/vtk/vtk/merge\_requests/4862/diffs#9cc788f89f8295fd16deed0c681d2837096b4b47\_282\_283](https://gitlab.kitware.com/vtk/vtk/merge_requests/4862/diffs#9cc788f89f8295fd16deed0c681d2837096b4b47_282_283)
Hope this helps!
