Hi. I am attempting to build OpenCV 4.6.0 with SFM module only for macOS arm64 architecture . Per the installation page for the SFM module, the dependencies are of the following:
- Eigen 3.2.2 or later
- Ceres
- glog
- gflags
For starters, I built a Ceres static library v2.1 with the following configuration:
- Eigen 3.4.0 installed via homebrew
- Using EigenSparse
- No SuiteSparse
- No CXSparse
- Using gflags v2.2.2 built from source
- Using glog v0.6.0 built from source
I then ran the sample binaries that were built and results were passing and no crashes just to verify it works.
With that, I used CMake GUI for OpenCV 4.6.0 config and set the Ceres_DIR variable to the directory with the CMake config file for Ceres, same goes for glog_DIR, Gflags_DIR, and gflags_DIR. For OPENCV_EXTRA_MODULES_PATH, I then set the value to the directory for the sfm module (*/opencv_contrib-4.6.0/modules/sfm) and pressed the Configure button.
The issue arose when I get the following CMake config output:
ocv_init_download: OpenCV source tree is not fetched as git repository. 3rdparty resources will be downloaded from github.com by default.

Module opencv_sfm disabled because opencv_xfeatures2d dependency can’t be resolved!
I wasn’t aware OpenCV sfm module needs xfeatures2d to be built. Am I missing something here? I am worried that this might become a dependency hell kind of problem should I continue to proceed with including xfeatures2d module in the build. That, and I’m not interested with using non-free 2D feature algorithms. If there is anyone here experienced with building/using SFM module, any guidance or assistance would be appreciated. Thank you.
