对于/etc/environment文件,不需要export关键字,直接添加变量即可: 代码语言:txt 复制 NEW_VARIABLE="value" 修改后,重新登录系统或重启服务使更改生效。 应用场景 路径配置:通过修改PATH环境变量,可以添加新的可执行文件搜索路径。 配置信息:应用程序可以通过环境变量获取配置信息,如数据库连接字符串、API密钥等。

对于CMakefile其他配置项,可以参考CMakefile是否存在,这类配置项都可以通过 cmake -D<Variable>=<Value>"进行设置。 # Set of indiviual options option(BUILD_SHARED_LIBS "Set to OFF to build static libraries" ON) option(WITH_SYSTEMD "Set to ON to create unit files and systemd check on dlt-daem...
CMAKE_INCLUDE_PATH 和 CMAKE_LIBRARY_PATH: 添加头文件和动态文件所在的搜索路径。这两个是环境变量而不是 cmake 变量,通过设置环境变量能够使得指定的路径先于系统路径被搜索。 # cat ~/profile export CMAKE_INCLUDE_PATH=/home/work/include export CMAKE_LIBRARY_PATH=/home/work/lib ...
