How to make FFTW ++ work with windows? (for Dummies)

Question

I use Windows 10 and Visual Studio 2015. In C ++, I need to get the Fourier transform of an image to apply filters to it. FFTW ++ seems to be the perfect solution for this, but I can't compile it, and it drives me crazy. I'm relatively new to programming, so I don't know how confusing this is.

I used the NuGet function in Visual Studio to get the FFTW library. Since I could not find it on NuGet, I downloaded the FFTW + material at the following link: https://sourceforge.net/projects/fftwpp/ I copied the contents of the download into the project folder and included the header files in the solution explorer. But he did not compile, threw many, many strange errors (for example: in seconds .h he said that some function that receives the time zone is outdated, and in fftww ++. H it was said that std :: max is illegal).

So, seeing that this did not work, I returned to the FFTW website and tried using the Windows installation guide. http://www.fftw.org/install/windows.html I downloaded the 64-bit version, and I absolutely do not know how to do this, for example, how to import a library or even what it does. i.imgur.com/Qs7mFQT.png That's all I get, I completely lost.

How do I assemble it? If you can: write me the most detailed explanation how to use this thing, I can be dumb, but I don’t know what is happening, and I can’t find any tutorial, for example, on Google.
