initial version

if it WAS opencv3.2, you simply could re-run cmake && make && make install. it would just overwrite the previous opencv main libs, no problem.

unfortunately, we're at 3.3-rc already.

there are 2 choices:

  • build latest version. update both opencv main and opencv_contrib to latest version. try a make uninstall before, then cmake && make && make install , as in your question.

  • stick with opencv3.2. download opencv_contrib v.3.2 and do cmake && make && make install . no uninstall needed.
