R Compilation gets stuck on Windows 64

In the file MkRules.local.in, I see the line: USE_ATLAS = NO which I believe
needs to be changed to YES. But how do I specify the BLAS file
libopenblas_haswell-r0.2.20.a and its location?

I have never done this, but a good starting point is searching the R
source code for how this works:
https://github.com/wch/r-source/search?utf8=?&q=USE_ATLAS

From the extra/blas/Makefile.win file it looks like you may need to

rename libopenblas_haswell-r0.2.20.a to libatlas.a and point to this
directory via the variable ATLAS_PATH in your MkRules.local.in?
