include_directories link_directories add_definitions

在CMake中，include_directories命令用于向项目中添加包含目录，以便编译器能够找到头文件。其格式如下：include_directories(\[AFTER|BEFORE\] \[SYSTEM\] directory1 \[directory2 ...\])。\[2\]

link_directories命令用于添加目录，以便链接器能够在其中查找库文件。其格式如下：link_directories(\[AFTER|BEFORE\] directory1 \[directory2 ...\])。\[1\]

add_definitions命令用于向项目中添加预处理器定义。其格式如下：add_definitions(-DDEFINE_NAME)。\[3\]

总结起来，include_directories用于添加包含目录，link_directories用于添加链接目录，add_definitions用于添加预处理器定义。
