QuantLib Python Installation

Question

I am trying to install QuantLib Python for Windows as per the instructions on this link; http://quantlib.org/install/vc10.shtml At first the file cstddef was not in the correct path and I had to search it and put it in the correct path. When I Build the Solution again, a new file stddef.h was not being found in Boost and I hatried to search for it in the Boost Folder but I did not find it. I managed to download the stddef.h file from the internet and I put it in the right path and when I Build the Solution again another new file yvals.h (1>C:\Program Files\Boost\boost_1_64_0\stddef.h(5): fatal error C1083: Cannot open include file: 'yvals.h': No such file or directory (compiling source file ql\experimental\math\particleswarmoptimization.cpp)) was not being found in the Boost Folder again. I did not find this file again in the Boost Folder and when I tried to download it on the internet it is being sold. Can Someone help on how I can have this file or if there is an easier way to do the installation.
