I have the same error，do you have any solution？

[zhouhao957]

Sorry, I didn't solve the problem. I think it has something to do with the version（ceres-solver ）
But I tried 1.4 and 2.0, both with the same error

POSSIBLE FIX

1. I didn't install the bugfix path from "ppa:bzindovic/suitesparse-bugfix-1319687"
2. There were two missing dependencies: libmpfr-dev and libgmp-dev. I installed them.
3. The variable defined at line 17 doesn't seem to be used and is wrong (absolute path): "set(Ceres_DIR "/home/maxjiang/Codes/ShapeDeform/3rd_party/ceres-solver/cmake/Ceres")". I just removed it.
4. In the MeshODE's CMakeLists.txt, there is a typo at line 132: "add_definitions(-D_GLIBCXX_USE_CXX11_ABI=1››)". The two last characters "››" are invalid and cause a preprocessor error when running the building commands. I removed them.

For now, everything builds...
