ake/ project 的初始化： VERSION 字段 • project( 项目名 VERSION x.y.z) 可以把当前项目的版本号设定为 x.y.z 。 • 之后可以通过 PROJECT_VERSION 来获取当前项目的版本号。 • PROJECT_VERSION_MAJOR 获取 x （主版本号）。 • PROJECT_VERSION_MINOR 获取 y （次版本号）。 • PROJECT_VERSION_PATCH 获取 z （补丁版本号）。 一些没什么用，但 CMake 官方不知为何就是提供了的项目字段…… 项目名的另一大作用：会设置另外 < 项目名 >_SOURCE_DIR 等变量 小技巧： CMake 的 ${} 表达式可以嵌套 因为 ${PROJECT_NAME} 求值的结果是 hellocmake 所以 ${${PROJECT_NAME}_VERSION} ${hellocmake_VERSION} 进一步求值的结果也就是刚刚指定的 0.2.3 了。 cmake_minimum_required 指定最低所需的 CMake 版本 假如你写的 CMakeLists.txt 包含了 3.15 版本才有的特性， 如果用户在老版本上使用，就会出现各种奇怪的错误。 因此最好在第一行加个 cmake_minimum_required(VERSION 3.15) 表示本
