[CMake] FindBLAS, FindLAPACK Modules and ACML Errors

[Lori A. Pritchett-Sheats]

I downloaded and installed the latest version of CMake 2.8.8. I found 
problems with the FindBLAS, FindLAPACK modules.

First thing I noticed was the ACML library search does not work for 
versions > 5.0. ACML no longer distributes acml_mv (multivector library) 
with ACML for versions > 5.0. FindBLAS only searches searches for acml 
and acml_mv libraries.

And then I ran into a very strange error with an older version of ACML. 
Simply calling FindBLAS when I did not set BLAS_ACML_LIB_DIRS, but I did 
have the ACML install in my LD_LIBRARY_PATH. Output from a very simple 
foo project that sets BLA_VENDOR to ACML and calls find_package(BLAS) 
and find_package(LAPACK):

Looking at the source, I believe there is an undefined list variable and 
a list(GET ...) call that is failing.
