Eclipses 如何支持CMake Project

eclipse目前版本（至少时Luna以后的版本）对Cmake有着特殊的支持。如果不用该支持，会导致index不完全，很多地方出现红线无法解析的问题。本文阐述实战中如何对MySQL（AliSQL）进行导入。

MySQL（AliSQL）的版本已经是Cmake。git clone后，进入文件夹：

发现里面有一个build.sh脚本，我们做相应的动作

mkdir bu

./build.sh

之后会在bu下生成一堆目录和文件，里面的.cproject就是cmake为我们生成的eclipse工程文件。之后eclipse打开已有项目文件即可。

让我们看一下build.sh做了什么。下面是build.sh的内内容：

#!/bin/bash## Script for Dev's daily work.

看到了吧。使用cmake的一般方式就是这样，先创建一个build文件夹（这里简写为bu），然后进入该文件夹，之后使用cmake .. 来进行compile。

注意，cmake的参数第一行，我添加的是-G"Eclipse CDT4 - Unix Makefiles"，目的就是生成.cproject文件。

进入到eclipse里（我用的时neon版本），加入本工程文件后，eclipse自动完成index，不用任何辅助设置。完美！
