can't disable ceres solver's output [miniglog]

Question

I'm using ceres solver for a project, and when I call the ceres::Solve function, the library starts to output lines such as this one:

CHOLMOD version 3.0.11, May 4, 2016: Symbolic Analysis: status: OK
  Architecture: Linux
    sizeof(int):      4
    sizeof(SuiteSparse_long):  8
    sizeof(void *):   8
    sizeof(double):   8
    sizeof(Int):      4 (CHOLMOD's basic integer)
    sizeof(BLAS_INT): 4 (integer used in the BLAS)
  Results from most recent analysis:
    Cholesky flop count: 1.8667e+05
    Nonzeros in L:       18060
  memory blocks in use:           7
  memory in use (MB):           0.1
  peak memory usage (MB):       0.2
  maxrank:    update/downdate rank:   8
  supernodal control: 1 40 (supernodal if flops/lnz >= 40)
  nmethods:   number of ordering methods to try: 1
    method 0: natural
        flop count: 1.8667e+05
        nnz(L):     18060

compressed_row_sparse_matrix.cc:171 # of rows: 2217 # of columns: 2217 max_num_nonzeros: 17748. Allocating 221848

the setting is:

    ceres::Solver::Options options;
    options.max_num_iterations = 200;  // 200: max number of iterations
    options.linear_solver_type = ceres::SPARSE_NORMAL_CHOLESKY;
    options.logging_type = ceres::SILENT;
    options.minimizer_progress_to_stdout = false;
    options.function_tolerance = 1e-8;  // 1e-8: Minimizer terminates when (new_cost - old_cost) / old_cost < 1e-8;
    ceres::Solver::Summary summary;
    ceres::Solve(options, &problem, &summary);

Does someone have an idea on how to disable this annoying log?
