+You can use CMake to configure Armadillo for Visual Studio, but you should modify your config.hpp file before compiling and installing. Make sure to explicitly link the libraries in the armadillo project. Also make sure that ARMA_USE_BLAS, ARMA_USE_ARPACK, ARMA_USE_LAPACK, ARMA_64BIT_WORD and ARMA_USE_CXX11 are enabled (the last two are technically optional and MLPACK will build without them).
 
 You can download the Boost libraries here: http://sourceforge.net/projects/boost/files/boost-binaries/1.60.0/
 
 You will have to modify CMakeLists.txt to prevent an error declaring MSVC as non C++-11 compliant. The patched file is included in the repo.
 You will have to modify any file containing OpenMP for loops, as MSVC 2015 supports OpenMP 2.5, which requires signed integer indices. GCC and Clang already support OpenMP 3.0 with unsigned indices. Replace "size_t" with "maxint_t".
 For 2.0.0 only src/mlpack/methods/det/dt_utils.cpp needs this fix.
