Using unordered_map and unordered_set C++ container types currently requires careful testing or usage of boost, due to the various confusing C++ version differences in include paths and namespaces. Libmv defines tests for these cases in cmake and scons, such that ceres can use any available implementation, or fall back too std::map/std::set if none can be found. This patch generalizes this buildfile code by providing a Blender macro. * cmake: defines both the variables used by libmv at them moment as well as 2 variables UNORDERED_MAP_INCLUDE_PREFIX and UNORDERED_MAP_NAMESPACE, which can later be used in other C++ parts for convenience. * scons: adds a tool script returning the include prefix and namespace. Libmv checks these to define the appropriate definitions for ceres. Differential Revision: https://developer.blender.org/D425 |
