If this is Unix(-alike) ....

You need libatlas.a, libcblas.a, libf77blas.a, and you want to specify
them as "-latlas -lcblas -lf77blas".  *However* they need to be in your
library path, and if they are, configure will find them.  So just

set the library path as needed (e.g. LIBS in config.site)
rm config.cache
./configure
make

will make use of ATLAS.  See the R-admin.html manual for more details.
