Build without avx2 #194

Closed Exdenta closed 4 years ago

Exdenta commented 4 years ago

Hi, I am just wondering, is there a way to build and use libfacedetection on cpu without avx2? My cpu supports only avx and when i'm building this project with -DENABLE_AVX2=OFF, build craches with this error:

(warning: I do not have more experience with this project than you do!)

In facedetectcnn.h lines 41..43: _ENABLE_AVX2 will be defined even if it previously wasn't. I commented out line 42 to allow it to run.

Thanks, that helped!
