用于缓存的 CMake 预加载脚本 [英] CMake preload script for cache

问题描述

我使用 -C mysettings.cmake 启动 cmake.

I fire cmake with the -C mysettings.cmake.

myfile.cmake 的内容是

The content of myfile.cmake is

set(CMAKE_INSTALL_PREFIX "C:/install/mylib" STRING)

一切都已生成，但似乎未设置 -C mysettings.cmake 变量.它仍然安装在默认目录中.

Everything is generated but it seems the -C mysettings.cmake variable is not set. It is still installed in the default directory.

Cmake 打印消息正在加载初始缓存文件 ../../script/cmake/mysettings.cmake"没有任何错误.

Cmake prints the message "loading initial cache file ../../script/cmake/mysettings.cmake" without any error.

完整的电话:

cmake -C ../../script/cmake/mysettings.cmake -G "Visual Studio 9 2008" ../../source/mylib

我的语法有问题吗?

推荐答案

来自 CMake 手册:

给定的文件应该是一个包含 SET 命令的 CMake 脚本使用 CACHE 选项，而不是缓存格式文件.

The given file should be a CMake script containing SET commands that use the CACHE option, not a cache-format file.

所以你的 myfile.cmake 需要看起来像这样:

So your myfile.cmake needs to look something like this:

set(CMAKE_INSTALL_PREFIX "C:/install/mylib" CACHE PATH "")
