g++: error: /usr/lib64/atlas/libsatlas.so: No such file or directory

Question

I am trying to compile this code https://thoth.inrialpes.fr/src/deepmatching/ which is supposed to be as simple as running the make command but am getting the error

I read online that it is because I am missing the atlas library so have tried running the command pip install atlas yet am still getting the same error. Could I get some advice please on how I can fix this.

As noted in the software's README.txt file:

This program has been built on a fedora18 x64 machine and tested on
Mac OS X.  *No assistance* will be given to compile the code on
other OS.

One way that appears to work (I've only tested it with ./deepmatching --help) is:

install the libatlas-base-dev package and its dependencies

run
 make clean
 make LAPACKLDFLAGS="$(pkg-config --cflags --libs blas-atlas)"

Note that this is almost certainly not the only way and quite possibly not the optimum way, since there is a multitude of different BLAS/LAPACK/ATLAS implementations available in Ubuntu. See for example What is the relation between BLAS, LAPACK and ATLAS
