On noetic, you have to call with following arguments

use_opencv3:=true use_opencv4:=true

opencv_apps/test/CMakeLists.txt

Lines 68 to 70 in e313986

	elseif("$ENV{ROS_DISTRO}" STREQUAL "noetic") # noetic uses opencv4 (need to use_opencv3 for some reason...)
	add_rostest(test-face_detection.test ARGS gui:=false use_opencv3:=true use_opencv4:=true)
	add_rostest(test-face_recognition.test ARGS gui:=false use_opencv3:=true use_opencv4:=true)
