make error: An implementation of BLAS is required but none was found.

hi!

When I was trying to install it from source I got error when make
make

The error message is as follow:

checking for sgemm_ in -lmkl_intel_lp64... no
checking for sgemm_ in -lmkl... no
checking for sgemm_ in -lopenblas... no
checking for ATL_xerbla in -latlas... no

make[2]: *** [faiss/src/faiss-stamp/faiss-configure] Error 1
make[1]: *** [CMakeFiles/faiss.dir/all] Error 2
make: *** [all] Error 2

Any idea why this is happening? How can I get around this problem?

Duplicate of #17

It's because faiss can't find the dependency. I am not sure how to solve that, since I never meet this in my environment. A workaround is to comment out all faiss related lines in CMakeLists.txt, if you don't need to use the visualization. Otherwise please refer to the above issue.

Thank for you reply!Please forgive me for being busy with other things and not replying to you.
I have solved this problem according to your method.
manually install OpenBLAS
compile faiss from source
compile graphvite with cmake .. -DFAISS_PATH=/path/to/faiss/ && make

But I have a new problem.When I was trying to install it from source I got error when executing
python setup.py install
I found that other people have encountered this problem.(#23)
ImportError: /home/deng/project/graphvite-0.1.0/build/lib/libgraphvite.so: undefined symbol: _ZN3fLS13FLAGS_log_dirE
Your suggestion is thart export the paths of gflags and glog into LD_LIBRARY_PATH.
But I did not solve this problem according to your suggestion.

My configuration：
Centos 7
python 3.7
conda install glog and gflags
CUDA 10.0

I am looking forward to your reply!Thanks! @KiddoZhu
