使用Cmake搭建Qt+VTK工程（順便推薦超好Cmake入門教程一本）

組內的項目要從MFC+OpenGL向Qt+VTK遷移。最近的任務是先把一個小模塊進行嘗試性遷移。

配置環境過程中發現Qt+VTK的項目配置起來十分麻煩，於是google之，發現使用CMake這個工具可以大大簡化我們的配置過程。可惜我從沒接觸過Cmake，於是再次google之，發現搜索到的相關教程都很是簡陋，不繫統也不實用。後來在機緣巧合之下找到了一份《Cmake 實踐》（http://sewm.pku.edu.cn/src/paradise/reference/CMake%20Practice.pdf），真是一本很好的快速入門教程，在此感謝作者。

花幾分鐘快速過一下，基本就可以動手了。結合網上的代碼片段，我終於寫出了自己的第一個Cmake腳本——可以把Qt和VTK結合起來，同時也展示瞭如何使用Cmake引入第三方庫。腳本貼在這裏供大家參考：

我在Cmake方面也還是菜鳥，以上代碼僅僅是達到能用的地步而已，缺點肯定是很多了，請各位高手多多指點！
