Build Error #error "Compiling with SSE2 enabled, but no __SSE2__ defined"

[Sezai Sablak]

Did anybody see the following error while building TheiaSfM? Am I missing any parameters or packages to be installed?
Thanks,
-Steve

Hi,

In order to build VLFEAT without SSE2 instruction you have to activate the VL_DISABLE_SSE2 preprocessor.
