Description

After searching a bit, I found this option to add compiler flags to configure.

../configure – -DCMAKE_CXX_FLAGS_RELEASE=-march=skylake

But the configure overview still says:

"Building for: linux-g++ (x86_64, CPU features: mmx sse sse2)"

Which means Qt isn't aware the cpu feature is enabled unconditionally (or the output is wrong).
