Error while configuring CMake to build with contrib modules

zabsy commented 1 month ago

OpenCV => 4.10.0
Operating System / Platform => Ubuntu 22.04.4
Compiler => CMake

Detailed description

Building OpenCV from source in order to use the SFM module, following the instructions here exactly, except replacing "4.x" with "4.10.0"

Steps to reproduce

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:

CMake Error at cmake/OpenCVUtils.cmake:1582 (add_library):

I tried to fix it by running sudo apt-get install libabsl-dev but I get the same errors.

Does anyone know how to fix this?

Thanks

OpenCV don't use abseil explicitly. Need to investigate which dependency is adding it to the project. Check ceres / glog / gflags and their versions.

Hello, I cannot reproduce this issue.

Install Ubuntu 22.04 (x86-64) on VMWare.
sudo apt install build-essential git ccache cmake libceres-dev
git clone https://github.com/opencv/opencv.git
git clone https://github.com/opencv/opencv_contrib.git
cmake -S opencv -DOPENCV_EXTRA_MODULES_PATH=./opencv_contrib/modules -B build4-main
It works well with 4.x branch , 4.10.0 tag from git and tar.gz packaged from releases.

probably related to this. @zabsy is your ceres built from source and version >=2.0?
