我想测试snappy library，但是在编译我的项目时，我有两个错误:

1>main.obj:错误LNK2019:未解析的外部符号“bool__cdecl snappy::uncompress（char const*，unsigned int，class std::basic_string，class std::allocator>*)”（？uncompress@snappy@@ya_npbdipav？$basic_string@du？$char_traits@d@std@@v？$allocator@d@2@@std@@@z)在函数_main中引用

1>main.obj:错误LNK2019:未解析的外部符号“unsigned int__cdecl snappy::compress（char const*，unsigned int，class std::basic_string，class std::allocator>*)”（？compress@snappy@@yaipbdipav？$basic_string@du？$char_traits@d@std@@v？$allocator@d@2@@std@@@z)在函数_main中引用

致命错误LNK1120:2个未解决的外部

我在我的项目属性中添加了带有lib和snappy32.lib的目录。
