GObject Introspection looks for a `babl-0.1` package which doesn't exist
On master
branch, in both my local build and the CI I see such warnings when building with meson:
Package babl-0.1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `babl-0.1.pc'
to the PKG_CONFIG_PATH environment variable
Package 'babl-0.1', required by 'virtual:world', not found
The pkg-config package is named babl
, not babl-0.1
so the fact it doesn't find it is not an error. It doesn't look like it breaks the build or GIR, but it's still annoying there is such a warning. We must probably do something wrong in our meson rules for GIR dependencies. We should fix this.
