PCL例程使用CMake导入VS2013失败
安装完PCL all_in_one 之后，使用CMake将例程生成为VS2013的工程
配置完成选择生成后界面如下：
有问题的有三行，如图红线所示：
1. OPENNI_INCLUDE_DIRS-NOTFOUND
2. OPENNI_LIBRARY-NOTFOUND
3. VTK_DIR-NOTFOUND
其中：1、2不是关键配置，只会导致警报。
3是导致生成失败的主要原因。
详细报错信息如下图所示：
Could NOT find openni (missing: OPENNI_LIBRARY OPENNI_INCLUDE_DIRS)
* WARNING * io features related to openni will be disabled
* WARNING * io features related to pcap will be disabled
* WARNING * io features related to png will be disabled

解决方案：
找到PCLConfig.cmake所在文件夹C:\PCL 1.7.2\cmake，将PCLConfig.cmake第293行
查看所安装PCL的VTKConfig.make所在的目录：
将PCLConfig.cmake第293行改为相应的目录：
