Then I have got a problem to compile (see http://answers.opencv.org/question/114601/error-while-building-opencv_contrib-with-eigen/)

cmake search the static gflags library by default, you shoud check your gflags whether static or shared.

[OtacilioNeto]

Hi. my old version of gflags was shared, but I rebuild it static and glog and ceres-solver but sfm detection still no working. :(

[LaurentBerger]

Do you use CMake GUI? If yes compare your config to my own config:

http://perso.univ-lemans.fr/~berger/Afsd56/bilan.png

May be you should update to ceres 1.12 too (not Found Ceres version: 1.11.0)
there is two egein path in cmake gui all must be fill with a good path

[OtacilioNeto]

Until now, the difference that I can see is that you are using OpenBLAS, but my CMake interface do not shows options to choose BLAS versions, except to CAND_BLAS.

[LaurentBerger]

I have found a difference I have copy this file in sfm/cmake

I have got one PR for glog and gflags too but I don't think you need it

[jasjuang]

On Ubuntu 16.04 and ran into a similar problem. Module opencv_sfm is only able to detect glog and gflags only if it's built as a shared library. If glog and gflags are installed from apt-get sudo apt-get install libgoogle-glog-dev libgflags-dev then it works fine because the library are shared. But if I want to get the latest update and build glog and gflags from source

git clone https://github.com/google/glog/
cd glog && mkdir build && cd build
cmake ..
sudo make install

git clone https://github.com/gflags/gflags
cd glog && mkdir build && cd build
cmake ..
sudo make install

A static library is built by default and opencv_sfm is unable to detect it causing it to not be built.
