do you resolve this issue????

I had the same problem as you, but I solved it this way.

solution

  1. When installing "ceres_solve", did you install the correct version? 2.1 version is stable, but 2.2 version should match the cmake version, so I recommend 2.1 is recommended.
  2. When proceeding with the "ceres_solve" tutorial, did the tutorial proceed perfectly? In my case, I ran "make install" because "make install" was written in the tutorial, but it didn't work. I ignored it and proceeded. As a result, "sudo make install" was satisfied. "
  3. The "ceres_solve" package must exit the work_station. In my case, I put it in the home folder, not the work_station folder. In this way, I had the same problem as you, but I solved it.
