MarsSeed [1] filed a deletion request for openni2-libfreenect [2]:
Abandoned package from 2016, broken as per last comment from that
year.
This is also a half-VCS package: it bundles two packages in one:
libfreenect (VCS) and openni2 (last version from 2014 which needs
patches to compile).
I recommend deletion, there is no need to keep this one:
AUR still has maintained libfreenect{,-} and openni2{,-git} packages.
