+[Intel(R) Distribution for Python*](https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/distribution-for-python.html).

+Patches were factored out per community feedback ([NEP-36](https://numpy.org/neps/nep-0036-fair-play.html)).

-MKLROOT=$CONDA_PREFIX python setup.py config_cc --compiler=intelem build_ext --inplace
+export MKLROOT=$CONDA_PREFIX
+python setup.py config_cc --compiler=intelem build_ext --inplace
