I have multiple version for opencv, but bibake installed the version 3.4.3 default.

=== Matching recipes: ===
opencv:
meta-rcar-gen3-adas 3.4.3+gitAUTOINC+b38c50b3d0_1f6d6f0626_bdb7bb85f3_34e4206aef_fccf7cd6a4
meta-oe 4.1.0
meta-rcar-gen3-adas 2.4.11+gitAUTOINC+707d10f115
meta-rcar-gen3-adas 3.2+gitAUTOINC+70bbf17b13


the yocto offical documents mentioned the variable RDEPENDS supports operator for specify versions.

then i specified the version to 4.1.0 for opencv in package group.

SUMMARY = "Requirement packages"
PR = "r1"

inherit packagegroup

RDEPENDS:${PN} = " \
opencv (>= 4.1.0)\
libopencv-core-dev \
libopencv-highgui-dev \

opencv-dev \

libgpiod \
libgpiod-tools \
"


Appeared the failure message, why??

The version list has v4.1.0, but the error message show nothing provides v4.1.0 for opencv.

nothing provides opencv >= 4.1.0 needed by packagegroup-user-requirements-1.0-r1.noarch

Successfully built the image after I try to set the version conditions as > 2.0, but the version still is v3.4.3 for opencv.

SUMMARY = "Requirement packages"
PR = "r1"

inherit packagegroup

RDEPENDS:${PN} = " \
opencv (>= 2.0)\

How to specify the package version via RDEPENDS in package group? thanks
