Cannot build on Ubuntu/16.04
Hi. I would like to make some modification on fastfm but I couldn't compile this fastfm-core module. I'm using Ubuntu/16.04 with gcc 5.4.0 .
Here is my compile error log. Looks it is a OpenBlas problem though.

By the way, the doc says I have to install OpenBLAS with apt-get but the makefile code looks just using extrenals/OpenBLAS, not system OpenBLAS. Is this build procedure correct?
I think our travis-ci runs 16.04, so this should really work.
Please make sure that you use --recursive in
git clone --recursive https://github.com/ibayer/fastFM-core.git
I assume you are building from the latest master?
the doc says I have to install OpenBLAS with apt-get but
Where? This is not correct anymore (OpenBLAS is included as sub-module).

Just tested again, this works for me on 16.04:
cd /tmp/
git clone --recursive https://github.com/ibayer/fastFM-core.git
cd fastFM-core
make
cd demo
make
make demo_lib
Makefile:123: *** OpenBLAS: Detecting CPU failed. Please set TARGET explicitly, e.g. make TARGET=your_cpu_target. Please read README for the detail.. Stop.
This was the direct cause. My CPU is Core-i7 7700k Kaby Lake and OpenBLAS failed to auto-detect its architecture. I added TARGET=HASWELL to my env and make was successful.
Maybe we should notice it in the doc.

Sorry, what the fastfm-core doc says to install was atlas (for cblas interface I suppose), not openblas. https://github.com/ibayer/fastFM-core#installation
# Install cblas (Linux only).
$ sudo apt-get install libatlas-base-dev
But the doc of fastfm itself still says to install openblas. (for cblas I suppose) https://github.com/ibayer/fastFM#installation
# Install cblas and python-dev header (Linux only).
# - cblas can be installed with libatlas-base-dev or libopenblas-dev (Ubuntu)
$ sudo apt-get install python-dev libopenblas-dev
Looks like a special case to me OpenBLAS: Detecting CPU failed. but adding a note to the README is a good idea.
We don't install OpenBLAS or ATLAS on our build machine https://github.com/ibayer/fastFM/blob/master/.travis.yml .
I believe neither is needed, but we should double check on a clean machine.
Thanks for reporting the issues. Feel free to open a PR to fix the docs.
FYI, the same openblas issue was reported in the official repo.

Thanks, that very good to know. So we should put a note in the README and update the OpenBLAS version as soon as a new release comes out (problem fixed in dev master).
