Fallback code paths with "SIMD Everywhere"

3

michaeleisel commented Aug 4, 2020

https://github.com/simd-everywhere/simde has done their first release ( https://simd-everywhere.github.io/blog/announcements/release/2020/06/21/0.5.0-release.html ) and it seems like something potentially useful for merging code paths. The most likely candidate I imagine is using SIMD code to replace the non-SIMD fallback path, but maybe it'd be worth checking if it can be used to merge ARM and x8

Prefix build options with "CT2_"

guillaumekln commented Jul 29, 2020

We should prefix CMake build options with "CT2_", e.g. CT2_WITH_MKL instead of WITH_MKL. This is a good practice to avoid possible conflicts with other projects.

The usage should then be updated in several places:
