使用SSH2 pecl扩展为Windows编译PHP的问题

我一直在跟着这个演练来编译PHP for Windows：
https://wiki.php.net/internals/windows/stepbystepbuild

要编译,我正在使用：
Microsoft Visual C Studio 2008 Express
Microsoft Windows SDK 6.1

我已经下载了SSH2所需的所有强制性libraries和库.我已经提取并将它们放在’deps’文件夹中.我还下载了SSH2扩展代码并将其放在我在’x86’目录中创建的’pecl’文件夹中.

看起来编译器没有找到我添加的库.任何帮助将不胜感激！谢谢！

以下是尝试使用以下命令进行编译时出现的一些错误：
