启用 CONFIGURE_DEPENDS 选项，当添加新文件时，自动更新变量 如果源码放在子文件夹里怎么办？ 必须把路径名和后缀名的排列组合全部写出来吗？感觉好麻烦 大可不必！用 aux_source_directory ，自动搜集需要的文件后缀名 进一步： GLOB_RECURSE 了解一下！能自动包含所有子文件夹下的文件 GLOB_RECURSE 的问题：会把 build 目录里生成的临时 这里初始化了一个名称为 hellocmake 的项目，为什么需要项目名？ 对于 MSVC ，他会在 build 里生成 hellocmake.sln 作为“ IDE 眼中的项目”。 CMAKE_CURRENT_SOURCE_DIR 表示当前源码目录的位置，例如 ~/hellocmake 。 CMAKE_CURRENT_BINARY_DIR 表示当前输出目录的位置，例如 ~/hellocmake/build 。 project 的 区别 PROJECT_SOURCE_DIR 表示最近一次调用 project 的 CMakeLists.txt 所在的源码目 录。 CMAKE_CURRENT_SOURCE_DIR 表示当前 CMakeLists.txt 所在的源码目录。 CMAKE_SOURCE_DIR 表示最为外层 CMakeLists.txt 的源码根目录。 利用 PROJECT_SOURCE_DIR 可以实现从子模块里直接获得项目最外层目录的路径。
