I met compilation error octomap/1.10.0 on gcc 5.4.

compilation error ``` In file included from ./octomap/include/octomap/OcTreeBaseImpl.h:83:0, from ./octomap/include/octomap/OccupancyOcTreeBase.h:44, from ./octomap/include/octomap/OcTreeStamped.h:39, from ./octomap/src/OcTreeStamped.cpp:34: ./octomap/include/octomap/OcTreeIterator.hxx:45:13: error: expected nested-name-specifier before ‘iterator_category’ using iterator_category = std::forward_iterator_tag; ^ ./octomap/include/octomap/OcTreeIterator.hxx:46:13: error: expected nested-name-specifier before ‘value_type’ using value_type = NodeType; ^ ./octomap/include/octomap/OcTreeIterator.hxx:47:13: error: expected nested-name-specifier before ‘difference_type’ using difference_type = NodeType; ^ ./octomap/include/octomap/OcTreeIterator.hxx:48:13: error: expected nested-name-specifier before ‘pointer’ using pointer = NodeType*; ^ ./octomap/include/octomap/OcTreeIterator.hxx:49:13: error: expected nested-name-specifier before ‘reference’ using reference = NodeType&; ^ In file included from ./octomap/include/octomap/OcTreeBaseImpl.h:83:0, from ./octomap/include/octomap/OccupancyOcTreeBase.h:44, from ./octomap/include/octomap/OcTree.h:38, from ./octomap/src/OcTree.cpp:34: ./octomap/include/octomap/OcTreeIterator.hxx:45:13: error: expected nested-name-specifier before ‘iterator_category’ using iterator_category = std::forward_iterator_tag; ^ ./octomap/include/octomap/OcTreeIterator.hxx:46:13: error: expected nested-name-specifier before ‘value_type’ using value_type = NodeType; ^ ./octomap/include/octomap/OcTreeIterator.hxx:47:13: error: expected nested-name-specifier before ‘difference_type’ using difference_type = NodeType; ^ ./octomap/include/octomap/OcTreeIterator.hxx:48:13: error: expected nested-name-specifier before ‘pointer’ using pointer = NodeType*; ^ ./octomap/include/octomap/OcTreeIterator.hxx:49:13: error: expected nested-name-specifier before ‘reference’ using reference = NodeType&; ^ ```

It seems to be caused by using type alias. type alias has been introduced C++11. ref

This PR ensures that C++11 is always used on CMakeLists.txt.
