This is a reference C implementation of the LZFSE compressor introduced in the Compression library with OS X 10.11 and iOS 9.
LZFSE is a Lempel-Ziv style data compression algorithm using Finite State Entropy coding. It targets similar compression rates at higher compression and decompression speed compared to deflate using zlib.

$ xcodebuild install DSTROOT=/tmp/lzfse.dst
Produces the following files in /tmp/lzfse.dst:
usr/local/bin/lzfse command line tool
usr/local/include/lzfse.h LZFSE library header
usr/local/lib/liblzfse.a LZFSE library
Tested on Ubuntu 15.10 with gcc 5.2.1 and clang 3.6.2. Should work on any recent distribution.
$ make install INSTALL_PREFIX=/tmp/lzfse.dst/usr/local
Produces the following files in /tmp/lzfse.dst:
usr/local/bin/lzfse command line tool
usr/local/include/lzfse.h LZFSE library header
usr/local/lib/liblzfse.a LZFSE library
$ mkdir build
$ cd build
$ cmake ..
$ make install
Installs the header, library, and command line tool in /usr/local.
