How about also testing for cblas before testing fro umfpack?


What I would suggest that the initial test is left as is. However if umfpack is not found then it would be tested with cblas as well, and if fond cblas would be added to the umfpack libraries... The build of umfpack seems to be really a bit of a mess...
