问题一
在参考如上连接进行pcl库和vtk的安装时，进行到pcl库的cmake编译时出现如下问题

Could NOT find OpenNI2 (missing:  OPENNI2_LIBRARIES OPENNI2_INCLUDE_DIRS) 
-- OpenNI2 grabber support: not building because OpenNI2 not found
-- Could NOT find ENSENSO (missing:  ENSENSO_LIBRARIES ENSENSO_INCLUDE_DIRS) 
-- IDS-Imaging Ensenso camera support: not building because Ensenso not found
-- Could NOT find davidSDK (missing:  DAVIDSDK_LIBRARY DAVIDSDK_INCLUDE_DIR) 
-- David Vision Systems SDK support: not building because davidSDK not found
-- Could NOT find DSSDK (missing:  DSSDK_LIBRARIES DSSDK_INCLUDE_DIRS) 
-- DepthSense SDK support: not building because DSSDK not found
-- Could NOT find RSSDK (missing:  RSSDK_LIBRARIES RSSDK_INCLUDE_DIRS) 
-- RealSense SDK support: not building because RSSDK not found

--   No package 'metslib' found
Could NOT find PCAP (missing:  PCAP_LIBRARIES PCAP_INCLUDE_DIRS) 
Could NOT find GLEW (missing:  GLEW_INCLUDE_DIR GLEW_LIBRARY)
