Use xz.exe unless program size is important.

Linking against liblzma
-----------------------
MinGW
If you use MinGW, linking against liblzma.dll or liblzma.a should
be straightforward. You don't need an import library to link
against liblzma.dll, and for static linking, you don't need to
worry about the LZMA_API_STATIC macro.
Note that the MinGW distribution includes liblzma. If you are
building packages that will be part of the MinGW distribution, you
probably should use the version of liblzma shipped in MinGW instead
of this package.
Microsoft Visual C++
Creating an import library for MSVC / Visual Studio

To link against liblzma.dll, you need to create an import library
first. You need the "lib" command from MSVC and liblzma.def from

If you need to link statically against liblzma, you should build
liblzma with MSVC 2013 update 2 or later. Alternatively, if having
a decompressor is enough, consider using XZ Embedded or LZMA SDK.
When you plan to link against static liblzma, you need to tell
lzma.h to not use __declspec(dllimport) by defining the macro
LZMA_API_STATIC. You can do it either in the C/C++ code
#define LZMA_API_STATIC
#include <lzma.h>
or by adding it to compiler options.
Other compilers
If you are using some other compiler, see its documentation how to
create an import library (if it is needed). If it is simple, I
might consider including the instructions here.
