When building on archlinux with gcc7(7.1.1) compiler complains about target specific option mismatch. Boosting -msse from 4.1 to 4.2 fixes the issue
gcc output:
g++ -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -pthread -I../../mve-git/libs -I../lib -msse4.1 -pthread -D_FORTIFY_SOURCE=2 -c -o bicubic_patch.o bicubic_patch.cc
