Felix Schwarz 2ff06c58f0 ability to use a system-provided version of "xxhash" ... The build process can be controlled via environment variables similar to other bundled libraries in borgbackup. The main difference is probably that upstream does not provide a pkgconfig file for xxhash. Therefore borg will probably fail to detect the system-provided version by default (tested on Fedora, seems like Debian and Ubuntu do not ship a pkgconfig file either). I kept the pkgconfig lookup code anyway to keep the code as similar as possible to "setup_compress.py"/"setup_crypto.py". Setting BORG_LIBXXHASH_PREFIX=/usr helps borg to detect xxhash on my system (Fedora). You can force the use of the bundled version of xxhash by setting BORG_USE_BUNDLED_XXHASH=1.		2019-06-04 21:59:26 +02:00
