What (if any) path for OpenNI should show up in environmental variables

Question

I recently had it pointed out to me that I might have OpenNI installed correctly but PCL is unable to access it. I've been trying to use various packages with the Kinect and when cmake compiling I always encounter the same error:

-- 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

I used printenv and received this output:

Does anyone have any ideas? Is this potentially a path issue?

Answer 1

It seems you have installed OpenNI into some non-standard ocation, that's why CMake can't locate it. Help it by setting CMAKE_PREFIX_PATH to the dir where OpenNI's include/ is located.
