target_include_directories 和include_directories

target_include_directories和include_directories都是在CMake中用于指定编译器搜索头文件的路径的指令。

target_include_directories用于为特定的目标（target）设置头文件搜索路径。具体语法为：
target_include_directories(<target> [SYSTEM [AFTER|BEFORE <INTERFACE|PUBLIC|PRIVATE> [items1...])
其中，<target>表示目标名称，表示将路径视为系统路径，用于指定添加路径的位置，<INTERFACE|PUBLIC|PRIVATE>表示添加路径的可见性， [SYSTEM dir1 [dir2 ...])
其中，用于指定添加路径的位置，表示将路径视为系统路径，dir1 [dir2 ...表示要添加的路径。

总结起来，target_include_directories用于为特定目标设置头文件搜索路径，而include_directories用于为当前目录及其子目录设置头文件搜索路径。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
