TBB version used in Windows binary distribution

Greetings,

Which version of Intel TBB is the latest version of Embree 2 (v2.17.5) built against in the Windows binary provided by Intel? We are using TBB for other parts of a program and need to find the TBB header files that align with the version of TBB that ships with said distribution. We would like to avoid re-compiling from scratch.

The release announcements for Embree 2 indicate they were last updated to TBB 2017 in Embree 2.12, that was a while ago, and when I right click on the tbb.dll that is bundled with v2.17.5 and examine its properties, I see 2017.0 and 2016.722 mentioned in Product version.

I suspect simply overwriting the TBB dll with the latest TBB releases DLLs would be a bad idea since Embree 2 was likely compiled against a different (major) version of TBB.

Thanks

Embree v2.17.5 from the ZIP file (https://github.com/embree/embree/releases/download/v2.17.5/embree-2.17.5.x64.windows.zip) is linked against TBB 2017.0 (https://github.com/intel/tbb/releases/tag/2017). You can figure this out by running ./verify when you downloaded Embree.
