The initial releases of the woff2 library have a bug with the pkg-config file: they do not directly pull in brotli. We have worked around this thus far by requiring it manually, but this should not be needed. Tom fixed it with https://github.com/google/woff2/commit/aff949b84713590907b259ecb49f630a19df55c0. A new version is now available with this fix, which we should use.
