+Description: cmake/modules/BuildRocksDB.cmake: inherit parent's CMAKE_CXX_FLAGS
+ CMake allows us to customize `CMAKE_CXX_FLAGS` by setting CXXFLAGS
+ environmental variable. and Debian's debhelper also sets CXXFLAGS
+ when it builds cmake projects for customizing the building flags.
+ .
+ but we fail to populate this setting down when building external
+ projects. this is important when it comes to the projects which
+ is critical to the performance. RocksDB is one of them.
+ .
+ in this change, we pass the `CMAKE_CXX_FLAGS` down in
+ `BuildRocksDB.cmake` so that its `CMAKE_CXX_FLAGS` contains
+ the same set of `CMAKE_CXX_FLAGS` used by its parent project.
+ .
+ this should help with the performance in the bluestore, where
+ RocksDB is used.
+ .
