GNU blas/lapack integer64 detection #259

Open miroi opened 5 years ago

miroi commented 5 years ago

Hi Rado,

as I see, GNU libraries lapack and blas are supporting integer-64 bit installation. Would be good to have math detection for 64bit integers.

Interesting! Yes I agree that this would be nice to support. I will soon return to this project and revive it.
