Hello,
I just realized SIFT was moved to xfeatures2d in opencv_contrib. I want to have the feature, so I am trying to compile the new module. However, It is disabled (see below). What dependency is Cmake referring to? (Im using Ubuntu 14.04. BTW, Cmake doesnt seem to find Qt, but this is a minor problem).

-- Disabled: world
-- Disabled by dependency: xfeatures2d
