what contrib_xfeatures2d does is to add cmake config for xfeatures2d (-DBUILD_opencv_xfeatures2d=ON). This 'work' in the sense that cmake is aware we want to build it: -- To be built: aruco bgsegm bioinspired calib3d ccalib core datasets dpm features2d flann freetype fuzzy hfs highgui img_hash imgcodecs imgproc java_bindings_generator line_descriptor ml objdetect optflow phase_unwrapping photo plot python_bindings_generator reg rgbd saliency shape stereo structured_light superres surface_matching tracking video videoio videostab xfeatures2d ximgproc xobjdetect xphoto But it actually fails: -- Unavailable: cnn_3dobj cudaarithm cudabgsegm cudacodec cudafeatures2d cudafilters cudaimgproc cudalegacy cudaobjdetect cudaoptflow cudastereo cudawarping cudev dnn_modern hdf java matlab ovis python2 python3 sfm ts viz xfeatures2d The reason, as far as my poor understanding of those cmake files goes, is that xfeatures2d depends on two downloadable ..."things": (modules/xfeatures2d/CMakeLists.txt): vgg and boostdesc But gentoo ebuild disable downloading: multilib_src_configure() {... -DENABLE_DOWNLOAD=OFF .. } It seems that lot of things are supposed to be downloaded, so my guess is that xfeatures2d is not the only one with this problem.
