System information (version)

ncurses => 6 (ncurses-devel)
OpenCV => 3.4 (opencv-devel)
Operating System / Platform => openSUSE Tumbleweed
Compiler => g++ 8 (gcc8-c++)

Detailed description

Incompatibility with opencv & ncurses.
I was using opencv2 on Debian, and today I moved to openSUSE Tumbleweed, which has opencv3, and my first make failed with this error (see attached file).

Steps to reproduce

If ncurses.h is included before opencv headers, build breaks.
Workaround: #include <opencv2/opencv.hpp> before #include <ncurses.h>
