Issue Description

I tried to compile and run the latest (v2.10.2) librealsense on a Up Squared computer with Pentium N4200 processor. The compiling was smooth and successful, but I got an error message when I run any librealsense tools or examples:

Illegal instruction (core dumped)

Actually I have run into the same issue with my own program on Up Squared computer with Celeron processor before, and I solved that time by add -msse3 flag to compiler (since Celeron does not support AVX2 instructions).

However, this time I still got the error even after I added -msse3 flag... So I was wondering anyone knows how to solve this? or has the same issue?

Thanks
