CMAKE修改VS总结

cmake(http://www.cmake.org/)的介绍，可以Google。

接触C++项目的人都知道，现在存在很多组织源代码进行编译的工具，windows平台下的nmake，visual studio（不同版本的sln project文件）以及Eclipse的CDT。cmake所处的位置，更像是这些已有工具的管理工具，它可以根据cmakelists文件来生成相应的makefile，project文件等等。

使用cmake的好处有很多。编写一次配置文件，就可以在不同的开发平台，不同的编译环境下使用。强大的定制功能，弥补很多工具自身的不足。自动化管理依赖，节省开发人员的时间和编译时间。等等。当然也有他的不足。每一个工具都是有自己的局限性。学习曲线比较陡峭。编译过程变的稍微复杂，需要首先生成中间格式的文件，然后才能编译生成最终的文件。学习资料很少很散。

有好处有坏处，需要的就是权衡。在我看来，cmake提供的功能比较诱人，将代码的配置信息与build环境剥离。这样做为程序员提供了很大的灵活性。

下载安装都很简单，直接到cmake的主页上下载安装包，按提示操作。

文件目录结构

在每一层目录下创建一个cmakelists.txt的文件，父目录的cmakelists文件可以指定包含的子目录，子目录的cmakelists则管理该目录下所有的sourcecode。目录可以多层嵌套，组织比较灵活，但是不建议目录层数太深。

Dir  Helloworld                                 The project
|      File  cmakelists.txt                     The project main cmakelists.txt, which should define the whole project’s properties and include sub dir
|      Dir  HelloworldTest                      The app dir, which contains the main function
|      |      File cmakelists.txt               The app cmakelists.txt, which defines all the source files, compiler flags and link flags.
|      |      File main.cpp                     The cpp file
|      Dir  Hellowould                          The library dir
|      |      File cmakelists.txt               The library cmakelists.txt, which should define all source files and build flags
|      |      File helloworld.h                 header file
|      |      File helloworld.cpp               cpp file

从上边的目录结构可以看出，每一层目录下边都有一个cmakelists.txt。

文件内容：

Helloworld/cmakelists.txt

CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )

project( Helloworld )

set( CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} /machine:x86" )

add_subdirectory( Helloworld )
add_subdirectory( Helloworldtest )

Helloworld/Helloworld/cmakelists.txt

CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )

set( HelloWorldSrc helloworld.cpp helloworld.h )

add_library( Helloworld STATIC ${HelloWorldSrc} )

Helloworld/HelloworldTest/cmakelists.txt

CMAKE_MINIMUM_REQUIRED( VERSION 2.8 )
set( HelloWorldTestSrc main.cpp)

include_directories( "${Helloworld_SOURCE_DIR}/Helloworld" )

add_executable( HelloworldTest ${HelloWorldTestSrc} )

target_link_libraries(HelloworldTest Helloworld )
add_dependencies( HelloworldTest Helloworld )

以上是最简单的cmake应用，使用了很基础的cmake命令，这里简单描述一下：

cmake_minimum_required( VERSION 2.8 ) ：表示当前cmakelists文件要求cmake版本最低为2.8

project( Helloworld ) ：整个项目的名字，在我们的项目中，Helloworld。这个在visual studio中对应solution的名字。

set( NAME VAL1 VAL2 ) ：设置变量NAME，值为VAL1;VAL2的列表。CMAKE中列表使用;分隔。如果需要空格分隔的结果，可以用双引号转换。

include_directories()：包含一个目录

add_executable(): 增加一个编译单元，目标文件为可执行文件，在windows上则为exe文件。

add_library()：添加一个编译单元，目标文件为库。

以上命令的详细解释，可以参考cmake的帮助文档。

Visual Studio属性与对应cmakelists实现方法

结论：CMAKE默认会修改的选项有时候是没有办法再次修改的。CMAKE默认不修改的选项大部分情况都可以自己定义。
