i've install OpenCV2.4.11 in my raspberry-pi, and few days ago i installed OpenCV3. There is no problem with the OpenCV3, but now i want to use back OpenCV2.4.11.
is there any way to use OpenCV2.4.11 instead of OpenCV3 without uninstall them?
i followed this tutorial when installing OpenCV3
when i first use OpenCV3, i made no changes at my cmakelists. thanks in advance
