Cura是著名的3D打印切片和控制软件。新的版本采用Qt和Python进行了重构，界面变化也非常大，目前还在开发中，运行问题还有不少。这里介绍如何从源代码进行Cura的编译，可以抢先体验新版的界面设计和根据需要进行订制。
这个把相关的脚本都集成到一起了。做了几个重要的改进，基本可以成功运行了。
主要的改进包括：
1、可以自动判断目录，如没有自动创建，如有则进行源码更新。原脚本安装后更新需要手工一步步进行，很麻烦。
2、改变gtest的安装源到github，原来的是从google下载，由于国内访问不到会导致编译出错。
3、合并 plugins目录，将Uranium\plugins复制到Cura\plugins下，避免找不到插件的错误。
注意：
1、进libArcus将Cmakelists.txt里的add_subdirectory(examples)这一行注释掉，要不编译不过去。
2、目前CuraEngine编译还有些问题，无法执行切片操作。
把下面的内容保存到cura.sh，然后sudo chmod +x cura.sh添加执行权限，然后./cura.sh就Ok了。需要的软件会自动下，时间较长，需要耐心等待。
#!/bin/bash
# This is a script which get the latest git repo and build them.
#
# Tested under ubuntu 15.04, lower versions don't have PyQT 5.2.1 which is required by cura
