Advantages  Replace header files  Modules explicitly state what should be exported (e.g. classes, functions, …)  Separation into module interface files and module implementation files is possible but not Improves build throughput; will be processed only once  Comparable to precompiled header files (PCH)  Custom headers can also be made importable, but how to is compiler dependent “How C++20

中添加一个可执行文件作为构建目标 另一种方式：先创建目标，稍后再添加源文件 如果有多个源文件呢？ 逐个添加即可 使用变量来存储 建议把头文件也加上，这样在 VS 里可以出现在“ Header Files” 一栏 使用 GLOB 自动查找当前目录下指定扩展名的文件，实现批量添加源文件 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？ Python 的 os.path.join(x, ‘bin’) 一样的效果。 毕竟大多数操作系统都是 Unix-like 嘛……就 Windows 喜欢搞特殊 。 cd /d C:\\Program\ Files\ \(x86\)\\Microsoft\ Visual\ Studio\\2019\\ 怎么路径里动不动夹杂几个转移符、空格、特殊符号？这谁顶得住啊 。 高情商： Windows 是最适合练习你 没加引号会怎样？会把列表里的字符串当成他的关键字 结论：除非确实需要列表，建议始终在你不确定的地方加上引号，例如： set(sources “main.cpp” “mylib.cpp” “C:/Program Files/a.cpp”) message(“${sources}”) 第 7 章：变量与缓存 重复执行 cmake -B build 会有什么区别？ 可以看到第二次的输出少了很多，这是因为 CMake
