Hmm, looks like I actually need both. Seems there is no easy way to get the cflags out of a source_set to construct a cpp command line.

Which makes this route less attractive ...
I was almost giving up... but it looks like the result of extract_all_objects(recursive: true) can be passed to custom_target(). Then you can match it after compile_commands.json's "output" key.

Any idea on getting the cflags in meson.build Or maybe I can somehow ask meson to run the cpp pass only for a given source set?
