I’m use Cmake for build a project with Camera Astra 3d. This project include opencv, When I build it with cmake comand I have a problem:

ubuntu@ubuntu-tos:~/src$ make

Hi,

i encountered the same issue.

May i know how you fixed the issue of “/usr/bin/ld: cannot find -lOpenNI2”?

Thanks in advance!

I have met this issue(quite similar). we just simply copy -lOpenNI2 to /usr/bin/ld but where?

Other solution I think is link to the libraray by command ln…ect…(please check that command).
