bzip2编译

1.源代码下载

源代码下载地址：https://sourceforge.net/projects/bzip2/files/，此处选择1.0.6版本下载。

2. windwos编译

先解压源代码到指定目录，查看bzip2代码目录，里面提供了vc5.0的工程（不要问为什么不是vc6.0，打开文件看一下就知道了）。

为方便跨平台构建和后续统一管理，这里使用cmake进行构建，在代码根目录创建一个CMakeLists.txt文件，内容参考zlib的CMakeLists.txt编写。

对于动态库的工程在vs中导出函数需要使用.def文件，不同编译选项生成的动态库文件名称不相同，这里还需要准备4个.def文件，文件中内容除了第一行不同，其他的都是一样的。
