Hello, I’m building OpenCV from source on Ubuntu 22.04.4 in order to use the SFM module, following the instructions [here](https://docs.opencv.org/4.x/d7/d9f/tutorial_linux_install.html?ref=wasyresearch.com) exactly, except replacing “4.x” with “4.10.0” After getting to the configuration step and running `cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.10.0/modules ../opencv-4.10.0` I get these errors: ```auto CMake Error at cmake/OpenCVUtils.cmake:1582 (add_library): Target "opencv_sfm" links to target "absl::log" but the target was not found.

hmm, it does NOT disable the sfm module by default ? (bc of missing absl deps ?) try to add `-DBUILD_open_sfm=OFF` to your cmake flags (you probably would not build that module anyway) then, let’s start a discussion on the contrib repo about this behaviour … ---

Thanks for the suggestion, however, I require the SFM module to build and work for what I’m using this for.
