I'm failing to build a project in c++ where OpenCV is used. Here is what I got:
/usr/bin/ld: cannot find -leigen
/usr/bin/ld: cannot find -lhighgui
/usr/bin/ld: cannot find -lcore
/usr/bin/ld: cannot find -leigen
/usr/bin/ld: cannot find -lhighgui
/usr/bin/ld: cannot find -lcore
But there are only libraries like "-lopencv_core" available nowadays. Is there any options how to fix this? I'm using Ubuntu.
