I think the documentation linked there is wrong - looking at the
release notes in the repository, it's 0.46 that mentions that new
feature, not 0.45:

https://github.com/mesonbuild/meson/blob/master/docs/markdown/Release-notes-for-0.46.0.md#improved-generation-of-pkg-config-files-for-static-only-libraries

I'll check if I can repro with 0.46 to confirm
