Lz4：Git Source
Lz4 Release：Git Release
Lz4源碼編譯：
找到lz4\visual，可以選擇VS2017和VS2010，本人使用的是VS2017
編譯：會報一些.h找不到的錯誤，修改屬性，VC++目錄添加包含目錄C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0\ucrt和庫目錄C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17134.0\ucrt\x86或者C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17134.0\ucrt\x64
找不到VS自帶的.h需要修改VS的安裝，選擇安裝標準庫模板（實驗性）解決方法
修改連接器，添加ucrtd.lib
使用：
下載的Lz4Release裏有Lz4.exe
Command Line Interface (CLI) supports gzip-like arguments.
By default CLI takes an input file and compresses it to an output file:
```
Usage: lz4 [arg] [input] [output]
```
The full list of commands for CLI can be obtained with `-h` or `-H`. The ratio can
be improved with commands from `-3` to `-16` but higher levels also have slower
compression. CLI includes in-memory compression benchmark module with compression
levels starting from `-b` and ending with `-e` with iteration time of `-i` seconds.
CLI supports aggregation of parameters i.e. `-b1`, `-e18`, and `-i1` can be joined
into `-b1e18i1`.
Lz4.exe -d input output：解壓縮，只識別.lz4後綴
Lz4.exe input output：壓縮
可以用-3到-16表示壓縮比越來越小
