This is incomplete, since this misses the compilation flags. This is actually a bit tricky and why I never went further.

The obvious ones are the target compile option (MSGPACK_USE_X3_PARSE needs fixing since it is set via CMAKE_CXX_FLAGS), the more tricky one is that you actually also needs to handle the Boost deps here.

There are two options:

  • export all the Boost flags to the .pc file (if there are any, would have to be checked)
  • never enable Boost (not nice since it breaks common workflows)

I would also move the default -I and -L flags directly in the pkg-config file as well, since they are static anyway and really only clutter the CMakeLists.txt
