HelloWorld for cmake

CMakeLists.txt とソースファイルの作成

#include <stdio.h>

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

cmake_minimum_required(VERSION 2.6.4)

# define a variable of project name
set( project_name "HelloWorld")

# set the project as the startup project
set_property(DIRECTORY PROPERTY VS_STARTUP_PROJECT ${project_name} )

# define a project name
project (${project_name})

# define a variable SRC with file GLOB
file(GLOB SRC *.c)

# define sources files of an executable
add_executable(${project_name} ${SRC})

• set( project_name "HellowWorld") で project_name という変数を HelloWorld という値で定義します
• set_property(DIRECTORY PROPERTY VS_STARTUP_PROJECT ${project_name} ) でproject_name という変数で定義したプロジェクトをスタートアッププロジェクトにします
• project (${project_name}) でプロジェクト名を定義します
• file(GLOB SRC *.c) で CMakeLists.txt と同じディレクトリにあるすべての *.c ファイルを SRC という変数に格納します
• add_executable(${project_name} ${SRC}) で SRC という変数に入っているソースファイルから project_name という変数で定義した実行ファイルを作成します
