follow [README.windows](https://github.com/JuliaLang/julia/blob/master/README.windows.md), on my magicbook (Intel Core i7-8550U), after almost 5 hours at least, done, BLAS and SuiteSparse cost most of time.

but only julia.exe under usr/bin, where is juila-debug.exe?

instructions are below:

```julia
make O=julia-win10x64 configure

echo 'XC_HOST = x86_64-w64-mingw32' > julia-win10x64/Make.user

make -C julia-win10x64

```

When you build from source, you normally don’t get the debug version.

> after almost 5 hours at least

Note that if you can use `-jN`, for example `make -C julia-win10x64 -j8`, and it will build in parallel with 8 processes.
