Port clBLAS to MacOS!

[oscarbg]

Presumably Accelereyes will use clMath in arrayfire for Macos so can we expect they will share port of clMath to MacOs here on github?

@oscarbg What compiler do you have in mind ? clang ? gcc ? Both ?

I am very interested in following the progress of this ticket as it relates to fommil/netlib-java#27

Being able to swap the default vecLib BLAS with clBLAS would be ideal in terms of end-user use of this library (even if it involves sudo moving some files around)

I'm able to compile on Mountain Lion with the instructions in my PR.

Somebody with better CMAKE foo than me could implement the include/linker changes.
