Inverse DFT slowdown with VS Cmake projects

Yes, there are debug/release and debug only configurations at the moment. But i’ve tested both in debug and both in release modes. iDFT slowdown persisted.
Considering IPP - to be honest, I’m not familiar with it. But as I understand it can speed up iDFT through optimized instructions, built specifically for Intel processors?
If I want to add IPP support, I assume I need to modify the CmakePresets.json with something like: “-D WITH_IPP=ON” command line option?

When I use cmake with opencv IPP is downloaded
with your json file I have no idea how to do
