Great! Done, thanks!

Another thought, it seems  a little unwieldy to add this block to the `CMakeLists.txt` for every package that wants to use this analysis 

# Enable thread safety annotations and analysis when using clang
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -stdlib=libc++ -std=c++14")

Would there be a better way to either
1. Put that block in for all ament packages, so it's enabled globally, but only affects code that is annotated using the C++ macros
2. Add a cmake macro/function to enable it as a one-liner, like `ament_enable_thread_safety_analysis`?

@Thomas_Moulard maybe you have thoughts on this?
