Invoking make error

[Jae0Kang]

Summary

I am working on Windows and face the issue on following the set up from https://github.com/facebookresearch/faiss/blob/main/INSTALL.md.
I checked step 1 (cmake -B build -DFAISS_ENABLE_GPU=OFF -DBLA_VENDOR=Intel10_64_dyn -DMKL_LIBRARIES=C:\Users\jykan\AppData\Local\Programs\Python\Python312\Lib\site-packages/mkl/libs -DFAISS_ENABLE_PYTHON=OFF -DBUILD_TESTING=ON .) worked well.

However, in step 2, I ran (make -C build -j faiss) and I got this message

make: Entering directory '/c/Users/jykan/Documents/faiss/build'
make: *** No targets specified and no makefile found.  Stop.
make: Leaving directory '/c/Users/jykan/Documents/faiss/build'

when I am trying to invoke make in faiss folder.

@Jae0Kang most likely, you need to put a number after j, so please try something like make -C build -j 8 faiss instead of make -C build -j faiss. Basically, -j parameter in make implies the number of CPU cores used during the compilation process. Maybe, there is an incompatibility for Windows.

@Jae0Kang have you tried on this one?
