Yann, All,
Thanks! Is there a link where I can see the output of the autobuilders? I'm happy to help fix anything that I'm breaking here.
Woody

Woodrow, All,
On 2022-11-17 12:34 -0500, Woodrow Douglass via buildroot spake thusly:

I just added a little comment in opencv4-contrib.mk as a reminder of
the situation.
That makes for a lot of options, and I was wondering if some may had
external dependencies. But I guess the autobulders will eventually tell
us so...

Applied to next, thanks.
