cmake学习

例子1：

命令：

# mkdir t1
# cd t1

# vim main.c
# vim CMakeLists.txt
# cmake .
-- This is BINARY dir/home/tomblack/文档/t1
-- This is SOURCE dir/home/tomblack/文档/t1
-- Configuring done
-- Generating done
-- Build files have been written to: /home/tomblack/文档/t1
# make
[100%] Built target hello
# ls
CMakeCache.txt  CMakeFiles  cmake_install.cmake  CMakeLists.txt  hello  main.c  Makefile
# ./hello
Hello World from t1 Main!

main.c的内容：

//main.c
#include <stdio.h>

int main()
{
    printf("Hello World from t1 Main!\n");
    return 0;
}

CMakeLists.txt的内容：

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

语法分析：

PROJECT:
    PROJECT(projectname [CXX] [C] [Java])
    用该指令定义工程的名称，并可以制定工程支持的语言，默认支持所有语言
