Exclude modules while building OpenCV

edit

you can disable building single modules like, e.g. cmake -D BUILD_opencv_objdetect=OFF

just be aware, that you can't build only objdetect, and not have core or imgproc, most of them depend on each other.

Thank you for your answer, where can I find the list of modules on which objdetect depends ?

see opencv/modules/objdetect/CmakeLists.txt

ocv_define_module(objdetect opencv_core opencv_imgproc opencv_ml OPTIONAL opencv_highgui)

so, that's core, imgproc, ml in this case

I want to do the same. What should i do?

@valium123 please be more exact. what do you want to do?
