I chose this method because ATLAS is a very special case:
- it is not packageable;
- it takes a very loooong time to build;
- I suspect that is not very optimized for modern CPUs.
Therefore I prefer not to use it as a direct dependency, but only for
machines where it has already been installed. For the other ones,
OpenBLAS is the default choice.
