Thanks a lot.   I set CMAKE_PREFIX_PATH and  'BLAS" was fuind.

HOWEVER I have the foollowing in /usr/local/atlas/lib.  

rt [ ~ ]$ ls /usr/local/atlas/lib
libacml_mp.so  libatlas.a   libcblas.a   libf77blas.a    libptcblas.a   
libptf77blas.a
libacml_mv.so  libatlas.so  libcblas.so  libf77blas.so   libptcblas.so  
libptf77blas.so
rt [ ~ ]$ 

Do you (or others on list know if  ALL  of these are  'found'  by  
FindBLAS.cmake?  I am asking this as  I have applications downstream 
that require linking to  -latlas -lf77blas and -lptf77blas  while others  the 
cblas(es).  A related question also IS:- does one need to set the LDFLAGS 
envar to be able to  set  "target_lib_libraries( -lxxx -lyyy )"  or are those 
invoked by a successful application fo FindBLAS.cmake ?
