External_python-scipy: Fix windows link error

[jcfr]

Based on the change of https://github.com/jcfr/SlicerSALT/commits/release-1.0, the windows build is getting further and fails with the following error:

"D:\D\S\SSALT-0-build\slicersources-build\python-scipy.vcxproj" (default target) (1) ->

Fixing this particular error is easy but it brings up another error. Even though the blas/lapack variables and path is set, it seems like the scipy build only searches python-install/Lib and python-install/libs for the blas and lapack libraries when linking. It seems like the easiest fix for this is to copy the files over there, is there any reason not to?

Sounds good to me.

Closing.

Following the Slicer update integrated python3 and the direct installation of scipy, there is no need to build it.
