How to use relative paths in build flags?

How can I use a path relative to workspace_dir as a build flag?

I am trying to add include folders. Eg: I would like to do the following:
build_flags =
-I ${workspace_dir}/utils/segger_rtt/RTT

Please let me know, the docs are not very clear on this and I tried different things without success

Just use -I utils/segger_rtt/RTT, PlatformIO will automatically resolve path from a current working directory (which is project directory).
