Source: libzstd Version: 1.4.5+dfsg-4 Severity: important Hello, I see you build an embedded xxhash.c/xxhash.h version of the xxhash library already in Debian.
I tried to use the system version, but some pre-processor directives such as XXH_NAMESPACE=ZSTD_ are tricking my efforts in crafting a patch, resulting into some undefined libraries when linking. Please consider asking upstream to detect and support (if possible) a system library, or add it to the list of embedded libraries in Debian G.
