Just copied out of one of my projects, should get you started: 
,----
| # math
| AC_LANG(C)
| AC_CHECK_LIB([m], [cos])
| dnl AC_CHECK_LIB([acml_mv], [cos])
| AC_CHECK_LIB([atlas], [ATL_xerbla])
| AC_SEARCH_LIBS([cblas_dgemm], [cblas gslcblas], [],
|                AC_MSG_ERROR([CBLAS is required.]))
| AC_CHECK_LIB([gsl], [main], [],
|              AC_MSG_ERROR([GNU Scientific library is required.]))
`----

If you have a more general version, I'd be interested to get a copy.

Greetings,
Jochen
