> bzip2 does not provide any information about its dependency (neither
pkg-config nor CMake files), so I think that would need an upstream patch
I agree with it.
Can we use `find_library()` as a workaround like the following?
```diff
diff --git a/cpp/src/arrow/meson.build b/cpp/src/arrow/meson.build
index fbd9cc8551..fd80539c80 100644

Can we use `dependency('snappy', 'Snappy')` for Snappy?
