Revision history [back]

i can only partly answer this, but here are some bulletpoints:

• there is a BUILD_LIST feature, where you can specify the modules you want , overriding the existing BUILD_opencv_xxxx=ON settings. you'd use it like:

  cmake -DBUILD_LIST=dnn,core,calib3d,imgproc,imgcodecs,highgui
  

  (comma seperated modulenames without opencv_ prefix)

• to pick up your xfeatures2d example: each module has a CmakeLists.txt, where you can find its dependancies , in this case:

  opencv_core opencv_imgproc opencv_features2d opencv_calib3d
  

  are mandatory. (... then you'll find out, that features2d needs flann ;)

• you have to carefully watch the cmake output for lines like:

  module xxxx disabled because of missing dependancy yyyy
  

  before you can run configure or make
