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`.
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.

void goto_set_num_threads(int num_threads);
void openblas_set_num_threads(int num_threads);

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.
