Eclipses 如何支持CMake Project-蒲公英云

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.

  while test $# -gt 0
  do
    case "$1" in
    -t=*)
      build_type=`get_key_value "$1"`;;

      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;;
