Thanks. It would've been a lot better if the build system hadn't caused so
blas, vector and copy benchmarks ran great. Sparse fails though...
That's because the matrix data files are missing. Try copying the testdata
folder from project root to the folder where the executable is located,
that should do it. I haven't automated this as these files are to be
replaced with an on-the-fly generation procedure in the near future.
And thanks for your feedback! I'm glad we can test the project on multiple
platforms to make it as robust as possible.
