When building the project as: ``` mkdir build && cd build cmake .. -DCMAKE_BUILD_TYPE=RELEASE ``` I get: >>> -- Opus library version: 0.8.0 -- Found Git: /usr/bin/git (found version "2.25.1") -- Opus package version: 1.3.1 -- Opus project version: 1.3.1 >>> the "Opus library version" is propagated in the pkg-config file (at the time of writing 0.8.0). I discovered this while building tag 1.3.1 locally. Including opus in my cmake project as `pkg_check_modules(OPUS REQUIRED "opus")` returned: > -- Found opus, version 0.8.0 I can live with it locally but I think it would good to fix it!
