这个软件的作用是将只能在linux上编译的软件用于在window上编译

下载 Cygwin

从官网上下载：https://www.cygwin.com/

每一次安装编译新软件都需要点击 setup.exe，如下图所示

这一页选择从互联网下载动态库

选择下载的文件夹，一路点下一步

这里选择下载源，我选的是阿里云的

这个页面选择要下载的动态库，通常去待安装的源码种查看依赖库，并从这个页面下载，如果需要再次下载，则点击 Cygwin 的setup.exe来到这个页面，再次选择要下载的动态库
选择下载完毕后，点击下一步进行安装即可，安装库完毕以后，重启一下Cygwin

以编译fastANI为例

从https://github.com/ParBLiSS/FastANI下载源码，并且放入 Cygwin 的目录下（与bin同级），解压缩到当前目录，然后查看 INSTALL.txt 的安装说明

mkdir build 
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .

如果在cmake的时候有缺少库报错，缺少哪一个则安装哪一个就可以，这里对CMakeLists.txt文件做了些许改动，

install(TARGETS fastANI DESTINATION bin)

set(CPACK_GENERATOR "TGZ")
set(CPACK_SOURCE_GENERATOR "TGZ")

include(CPack)

打开 cygwin 终端，然后按照INSTALL.txt进行编译和安装：

mkdir build 
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release [--install-prefix ...  -DGSL_SHARED=... -DGSL_ROOT_DIR=... -DBOOST_ROOT=...]
cmake --build .

就可以在 build 文件夹下生成 fastANI.exe文件了

这里会有报错：

缺少哪一个模块，则去 Cygwin/bin 中将缺少的文件复制到 fastANI中的build文件夹下即可，移动时模块与fastANI.exe要一起移动

检查下效果：

OK了
