+// Default (empty) configuration options for Ceres.
+//
+// IMPORTANT: Most users of Ceres will not use this file, when compiling Ceres
+//            with CMake, CMake will configure a new config.h with the currently
+//            selected Ceres compile options in <BUILD_DIR>/export, which will
+//            be added to the include path for compilation, and installed with
+//            the public Ceres headers.  However, for some users of Ceres who
+//            compile without CMake (Bazel), this file ensures that Ceres will
+//            compile, with the user either specifying manually the Ceres
+//            compile options, or passing them directly through the compiler.
