I recently updated to 3.4. (at Win7 64bit, mingw64) read the official tutorial for installing, and also about Intel TBB.
My question: Is TBB still useful/ recommended when building OpenCV?
And if - I tried to - how to do it? As I got problems when doing as described in the tutorial: Where to put the TBB tree? Which selection do in CMake? I get:
"BUILD_TBB option supports Windows on ARM only! Use regular official TBB build instead of the BUILD_TBB option!"
