查找 boost 库时抛出错误

Question

我正在尝试编译一个使用 Boost 的 C++ 项目。我已经在 Windows 机器上尝试过这个（首先尝试使用 cygwin，然后使用 Visual Studio）以及 Macbook。我继续遇到cmake 会发现 Boost 就好了，但make 会告诉我它找不到它需要寻找的第一个 boost 库的问题。我试过使用make -I/path/to/boost/parent/directory/ 并且输出是相同的。

我在下面附上了cmake .. 和make 的Mac 终端输出。我还将包括我采取的步骤，并尝试剖析问题：

1. 跑brew install boost
2. 跑git clone git-repo
3. 跑mkdir buildcmake ..make

我还重新安装了 boost，重新安装了 brew，并检查了编译器是否使用了正确的包含路径。 CMakeLists.txt 有find_package(Boost REQUIRED) 行。执行所有这些操作会产生如下所示的相同结果。

任何解决此问题的帮助将不胜感激。

我已经解决了这个问题。在 CMake 文件中添加行 include_directories(/path/to/libraries/) 就足够了。
