set 表示CMake 将设置相应的值,而 external 表示CMake 将不会设置相应的值。建议将 set 与IDE 生成器(如 Visual Studio 生成器)配合使用。 将 external 与命令行生成器(如 Ninja)配合使用。 通过这些值,Visual Studio 等供应商可在调用 CMake 之前提供所需的环境。 若要详细了解体系结构和工具集字段,请参阅...
If CMakePresets.json is your active configuration file, you'll need to set the path to vcpkg.cmake in CMakePresets.json. We recommend using the VCPKG_ROOT environment variable instead of an absolute path to keep the file shareable. For more information, see Enable vcpkg integration with CMa...
在了解 CMake 的基本概念和用法之后,作为一种编程语言,还是得从最基本的变量,流程控制(for 循环,if 条件),函数等开始学习。在最开始,我们强调一点——CMake 作为一门语言是区分大小写的!只是具体到通常使用的内置命令/自定义函数/自定义宏,不区分大小写。
if (${POOL_SIZE}) set(WORKER_POOL_SIZE ${POOL_SIZE}) endif () configure_file(config.h.cmake config.h) POOL_SIZE是在运行cmake的时候传进来的参数,在cmake中,要传一个参数可以使用-D选项,比如: cmake ../src -DPOOL_SIZE=100 我们判断POOL_SIZE是否设置,如果设置了,那就设置WORKER_POOL_SIZE变...
