I'm no expert, but the FAQ says:

"You have a GPLed program that I'd like to link with my code to build
a proprietary program. Does the fact that I link with your program
mean I have to GPL my program? (#LinkingWithGPL)

Not exactly. It means you must release your program under a license
compatible with the GPL (more precisely, compatible with one or more
GPL versions accepted by all the rest of the code in the combination
that you link). The combination itself is then available under those
GPL versions."

So my understanding is that it's ok for a program to link to FlexiBLAS
if its license is GPL-compatible, not necessarily GPL. But of course
we would need confirmation from legal.
