解决⽅法
参考⽂章：
您可以添加包含libclamav的⽬录。lib库⽂件到LIBPATH解决这个问题(这个说明可能会有所不同，取决于你的Visual Studio版本)：在“解决⽅案资源管理器”中，右键单击项⽬，然后单击“属性”。
在“属性页”对话框中展开“链接器”，然后单击“常规”。
在附加库⽬录字段中，指定libclamav所在的路径，libclamav.lib
当LIBPATH包含空格时也可能发⽣错误。如果是这种情况，请将库移动到没有空格的路径上，或者在路径周围加上引号。
我希望我能给你1000个赞!我试图更新⼀个遗留项⽬，LIBPATH中有空格！我已经了好⼏个⼩时了，没⼈告诉我。我不知道它在原来的开发环境中是如何⼯作的!也许他们碰巧也有它在LIB环境……⽆论如何，我不知道更现代的VS版本是如何处理这个问题的，但是vc++ 6(别问了!)并没有优雅表⽰。- 5⽉19⽇14时9分12秒
为了防⽌别⼈⽆意中发现我的错误，我犯了⼀个更基本、更愚蠢的错误。我试图在“仅在项⽬中”构建。确保先构建您的依赖项!右键点击你的项⽬⽂件，然后点击build。- 12⽉22⽇15时20分47秒
