While installing opencv_contrib (during make -j5 step), my laptop went to sleep and gave errors on the install, failing with a fatal error.
Retrying make -j5 gave the same error again. trying to uninstall opencv completely using make uninstall also completely fails with a fatal error.
How do I do a fresh install of OpenCV from here?
Error on running make uninstall:
-- Uninstalling "/usr/local/include/opencv2/cvconfig.h"

You should try make clean and try to uninstall again. Also you should restart from previous steps for opencv installing
