学习写hello world
配置好cmake环境后
创建CMakeLists.txt

PROJECT (HELLO)
SET(SRC_LIST hello.c)
MESSAGE(STATUS "This is BINARY dir " ${HELLO_BINARY_DIR})
MESSAGE(STATUS "This is SOURCE dir "${HELLO_SOURCE_DIR})
ADD_EXECUTABLE(hello ${SRC_LIST})

创建hello.c

#include <stdio.h>

int main()
{
    printf("Hello World.\n");
    return 0;
}

运行cmake

cmake .
myfly@ubuntu:~/mycmake/hello$ cmake .
