From: Woody Douglass via buildroot @ 2022-11-03 22:30 UTC (permalink / raw)
  To: buildroot@buildroot.org
  Cc: fontaine.fabrice@gmail.com, thomas.petazzoni@bootlin.com

This adds a separate opencv4_contrib package to manage
downloading/unpacking that repository. These extra modules
are useful for a lot of applications, but not necessary
for minimal installs, so they are all given dedicated Kconfig
options
