  "message": "Only use LTO when compiling Ceres itself, not tests or examples.\n\n- If Ceres is built as a shared library, and LTO is enabled for Ceres\n  and the tests, then type_info::operator\u003d\u003d() incorrectly returns false\n  in gtests\u0027 CheckedDowncastToActualType() in the following tests:\n-- levenberg_marquardt_strategy_test.\n-- gradient_checking_cost_function_test.\n  on at least Xcode 6 \u0026 7 as reported here:\n  https://github.com/google/googletest/issues/595.\n- This does not appear to be a gtest issue, but is perhaps an LLVM bug\n  or an RTTI shared library issue.  Either way, disabling the use of\n  LTO when compiling the test application resolves the issue.\n- Allow LTO to be enabled for GCC, if it is supported.\n- Add CMake function to allow easy appending to target properties s/t\n  Ceres library-specific compile flags can be iteratively constructed.\n\nChange-Id: I923e6aae4f7cefa098cf32b2f8fc19389e7918c9\n",
