cmake入门 step1 （一行cmake语句）

文件树：

├── build├── CMakeLists.txt├── hello.c

CMakeLists.txt

ADD_EXECUTABLE(hello hello.c)

hello.c

#include<stdio.h>int main(){    printf("hello world ^_^ \n");    return 0;}

执行命令

cd buildcmake ..make./hello

输出结果

hello world ^_^

可以尝试添加打印一些信息

PROJECT(project1)MESSAGE(STATUS "The BINARY dir is ${PROJECT_BINARY_DIR}")MESSAGE(STATUS "The SOURCE dir is ${PROJECT_SOURCE_DIR}")SET(SRC_LIST hello.c)MESSAGE(STATUS "The SOURCE list is ${SRC_LIST}")ADD_EXECUTABLE(hello hello.c)

执行cmake 会出现

-- The BINARY dir is /home/chuny/test/step1/build-- The SOURCE dir is /home/chuny/test/step1-- The SOURCE dir is hello.c
