Thank you all for your feedback and advice.
For testing,
- emerge media-libs/opencv-4.10.0
- some time later CTRL+C to stop compilation

Then I followed Jack's advice
- ebuild /var/db/repos/gentoo/media-libs/opencv/opencv-4.10.0.ebuild compile
- ebuild /var/db/repos/gentoo/media-libs/opencv/opencv-4.10.0.ebuild install
- ebuild /var/db/repos/gentoo/media-libs/opencv/opencv-4.10.0.ebuild qmerge

Everything worked fine, thanks a lot.

Good evening to all,

Best regards,
