Am getting the linking error below when building on Windows with python 3.10.4, the latest MSVC 2019 and MKL 2024.2.0. I also have the recommended rtools installed. I’m using this command to build:
python -m pip install . -Csetup-args=-Dblas=mkl -Csetup-args=-Dlapack=mkl --verbose
What I am doing wrong?
