-Wno-inconsistent-missing-override - Build Error OpenCV 4.5.0

edit

I am attempting to compile the OpenCV package on a small ARM processor. Using essentially the same process I can compile on a Raspberry Pi but not on my RockChip system.

There is no relevant text "no-inconsistent-missing-override" In the 4.5.0 downloads. I expect it's being automatically generated by gcc or cmake?

My RockChip O/S is Armbian variant Debian Buster.

Linux nanopim4v2 5.8.17-rockchip64 #20.08.21 SMP PREEMPT Sat Oct 31 08:22:59 CET 2020 aarch64 GNU/Linux

GCC and cmake default settings are

gcc -v
Using built-in specs.
