Simply invoking `make` (or `gmake` on BSD) will detect the CPU automatically. Simply invoking `make` (or `gmake` on BSD) will detect the CPU automatically.
To set a specific target CPU, use `make TARGET=xxx`, e.g. `make TARGET=NEHALEM`. To set a specific target CPU, use `make TARGET=xxx`, e.g. `make TARGET=NEHALEM`.
The full target list is in the file `TargetList.txt`. The full target list is in the file `TargetList.txt`. For building with `cmake`, the
usual conventions apply, i.e. create a build directory either underneath the toplevel
OpenBLAS source directory or separate from it, and invoke `cmake` there with the path
to the source tree and any build options you plan to set.

Note that these are only used once at library initialization, and are not available for
fine-tuning thread numbers in individual BLAS calls.
If you compile this library with `USE_OPENMP=1`, you should use the above functions too. If you compile this library with `USE_OPENMP=1`, you should use the above functions too.
