[~] Automatically tracked dependencies between modules [+] Support for optional module dependencies [+] Options to choose modules to build [~] Removed hardcoded modules lists from OpenCVConfig.cmake, opencv.pc and OpenCV.mk [+] Added COMPONENTS support for FIND_PACKAGE(OpenCV) [~] haartraining and traincascade are moved outside of modules folder since they aren't the modules
