Mandatory DLLs for MKL and Fortran.
MKL package and Fortran package installezd by pip
copy the DLLs to the Library/bin folder of Python.
This folder may not be in the PATH, so we need
to copy the DLLs to the wolfhece's libs folder.
Depending on the Python installation, the Library/bin
folder may be in different locations. We search for it
in the main directory of the Python interpreter and
in the different site-packages folder.
