title: How to get FFTW++ working on windows? (for dummies)
body: <p>I'm using Windows 10 and Visual Studio 2015. In C++, I need to get the Fourier-transform of an image for applying filters on it. It seems that FFTW++ is the ideal solution for this, however I can't get it to compile, and its driving me mad. I'm relatively new to programming so I don't know how embarrassing this is.</p>
  
  <p>I used the NuGet function in Visual Studio to get the FFTW library.
  Since I couldn't find it on NuGet I downloaded the FFTW+ stuff from the following link: <a href="https://sourceforge.net/projects/fftwpp/" rel="noreferrer">https://sourceforge.net/projects/fftwpp/</a>
  I copied the content of the download to the project folder, and included the header files in the solution explorer. But it didn't compile, thrown many-many weird errors (for example: in the seconds.h it said that some function which gets the timezone is obsolete, and in the fftww++.h it said that std::max is illegal).</p>
  
  <p>So after seeing that this isn't going to work I went back to the FFTW website, and tried using the Windows installation guide. <a href="http://www.fftw.org/install/windows.html" rel="noreferrer">http://www.fftw.org/install/windows.html</a>
  I downloaded the 64-bit version, and I have absolutely no idea how to do the library import thing, or even what it does.

  This is all I get, I'm completely lost.</p>
  
  <p>How can I get it to compile?
  Please if you can: write me an explanation as detailed as possible on how to use this thing, I may be dumb but I literally have no idea what is going on, and I can't find any tutorial-like on Google.</p>
