From iwdevtools: ``` $ qa-vdb dev-cpp/fbthrift VDB: detected possibly incorrect RDEPEND (dev-cpp/fbthrift-2024.11.04.00) > app-arch/bzip2 > app-arch/lz4:= > app-arch/snappy:= > app-arch/xz-utils dev-cpp/mvfst:= < > dev-libs/double-conversion:= > dev-libs/libaio > dev-libs/libfmt:= > dev-libs/libsodium:= dev-libs/xxhash:= | dev-libs/xxhash > sys-libs/liburing:= ``` A bunch of these deps need adding as they're currently automagic (or unconditionally used but not depended on), or may be possible to add USE flags for some of them. I've added the libfmt dep but the others need looking at, ditto the rest of the FB suite.
