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.  It is a good idea to use the exact same
    # build options as the released version.
    
    get_key_value()
    {
      echo "$1" | sed 's/^--[a-zA-Z_-]*=//'
    }
    
    usage()
    {
    cat <<EOF
    Usage: $0 [-t debug|release] [-d <dest_dir>] [-s <server_suffix>]
           Or
           $0 [-h | --help]
      -t                      Select the build type.
      -d                      Set the destination directory.
      -s                      Set the server suffix.
      -h, --help              Show this help message.
    
    Note: this script is intended for internal use by MySQL developers.
    EOF
    }
    
    parse_options()
    {
      while test $# -gt 0
      do
        case "$1" in
        -t=*)
          build_type=`get_key_value "$1"`;;
        -t)
          shift
          build_type=`get_key_value "$1"`;;
        -d=*)
          dest_dir=`get_key_value "$1"`;;
        -d)
          shift
          dest_dir=`get_key_value "$1"`;;
        -s=*)
          server_suffix=`get_key_value "$1"`;;
        -s)
          shift
          server_suffix=`get_key_value "$1"`;;
        -h | --help)
          usage
          exit 0;;
        *)
          echo "Unknown option '$1'"
          exit 1;;
        esac
        shift
      done
    }
    
    dump_options()
    {
      echo "Dumping the options used by $0 ..."
      echo "build_type=$build_type"
      echo "dest_dir=$dest_dir"
      echo "server_suffix=$server_suffix"
    }
    
    if test ! -f sql/mysqld.cc
    then
      echo "You must run this script from the MySQL top-level directory"
      exit 1
    fi

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！
