How do I solve this OpenNi dependency error in PCL when using the Kinect?

Although I've just signed up for Stackoverflow, I've used answers.ros.org, pcl-users.org, and other similar sites. I'll try to give as much information as possible because although similar problems come up in Google searches I cannot find an answer to this.

I'm running Ubuntu 12.04 and I've installed PCL 1.7 via their set of instructions here: http:// pointclouds.org/downloads/linux.html

Following the tutorials I was able to get the "reader" and "writer" sample programs to work with the sample PCD's they give. I was also able to successfully use cmake to compile a more advanced program: http://pointclouds.org/documentation/tutorials/normal_distributions_transform.php#normal-distributions-transform

The problem begins whenever I try to make the iograbber or any other visualization programs that involve the Kinect. This is specifically the one I really want to use: http://pointclouds.org/documentation/tutorials/openni_grabber.php#openni-grabber Repeatedly, without fail, this has always been the warning I encounter when using cmake:

-- checking for module 'openni-dev'

-- package 'openni-dev' not found

-- Could NOT find openni (missing: OPENNI_INCLUDE_DIRS)

** WARNING ** io features related to openni will be disabled

It gives this warning several times in a row related to various components checking for it. Now you might say, "silly user, why don't you simply install openni-dev?"

Well when I initially did it with sudo apt-get install -y openni-dev (notice the -y which I soon learned about) it deleted most of my ROS/PCL files. Thread is here: http:// www.pcl-users.org/How-can-I-get-PCD-files-from-a-streaming-Kinect-td4033721.html It broke some packages and long story short I found out about aptitude and eventually I got myself back to square 1.

The thing is, I'm fairly sure I have openni 1.5.4 installed but somehow it isn't being found. When I go to my usr/lib folder it only shows an OpenNI2 folder, and not an OpenNI folder. I know there's a lot of issues with openni-dev popping up for PCL and ROS so I hope this answer will be able to help others as well. Before you ask, I'm copying/pasting the CMakeLists and C++ files exactly as I find it. I don't have a lot of programming experience so I hope I'm not missing something obvious.

If you use kinect v2, there's no OpenNI support. So you can use this grabber:https://github.com/UnaNancyOwen/KinectGrabber/tree/Kinect2Grabber
