公共标头找不到其他公共标头

Question

我使用CMake创建了一个静态库，并将公共头文件安装在/usr/local/include/中。这个库和它的测试本身编译得很好，但是当在另一个项目中使用这个库时，我得到一个错误：

/usr/local/include/weftworks/common/network/tcp/acceptor.hpp:28:10: fatal error: utility.hpp: No such file or directory
 #include "utility.hpp"

其中acceptor.hpp和utility.hpp都是公共标头。

下面是相关的文件夹结构：

root/
├ cmake/
├ external/
├ library/
│ ├─ include/
│ │  ├─ network/
│ │  │  └─ tcp/
│ │  │     └─ acceptor.hpp
│ │  └─ utility.hpp
│ ├─ src/
│ └─ CMakeLists.txt
├ test/
└ CMakeLists.txt

现在我不知道我需要做什么才能让它工作。为了简单起见，我希望避免在项目结构中使用“库前缀”，即library/include/weftworks/common/。

Answer 1

您需要包含"weftworks/common/network/utility.hpp"。

这还将确保您实际上包含了您的头，而不是某些人用非常通用的名称"utility.hpp"编写的其他头。
