-- Detected available Ceres threading models: [CXX_THREADS, NO_THREADS]
-- Building with C++14
-- Found Eigen version : 
-- Enabling use of Eigen as a sparse linear algebra library.
-- Building without LAPACK.
-- Building without SuiteSparse.
-- Building without CXSparse.
-- Found Apple's Accelerate framework with sparse solvers, building with Accelerate sparse support.

-- Compiling minimal glog substitute into Ceres.
-- Using minimal glog substitute (include): internal/ceres/miniglog
-- Max log level for minimal glog substitute: 2
-- Using Ceres threading model: CXX_THREADS
-- Failed to find Google benchmark library, disabling build of benchmarks.
-- Building Ceres as a static library.
-- Do not build any example.
