Pull Request Readiness Checklist

See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request

• I agree to contribute to the project under Apache 2 License.
• To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV
• The PR is proposed to the proper branch
• There is a reference to the original bug report and related work
• There is accuracy test, performance test and test data in opencv_extra repository, if applicable
  Patch to opencv_extra has the same branch name.
• The feature is well documented and sample code can be built with the project CMake

I did not test every configuration and build option, module, and sample. All I did was search all the code for cmake_minimum_required, look for ones less than 3.5, and bump them. I can report that my build like below succeeded with my branch:
cmake -B build -G Ninja -D CMAKE_INSTALL_PREFIX=$FINAL_INSTALL_DIR -D BUILD_LIST=tracking -D OPENCV_GENERATE_PKGCONFIG=YES -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -D WITH_OPENMP=ON

(Yes, I do prefer to separate my -Ds from the option.)
