How to manage CPU-specific features in package ?

[Aaron Boxer <boxerab@gmail.com>]

Hello,

My library can use SIMD vector operations such as AVX2 if available on system.

What is the best way of managing this ?  For simplicity, I could create two packages, one with all SIMD disabled, and one assuming AVX2. What's the standard way of approaching this?

Also, I tried logging onto #debian-mentors on freenode, but I got a message about

"invite only channel"

Thanks,

Aaron
