Getting an error while trying to make an Android Build

Building Library\Bee\artifacts\Android\d8kzr\c20n4nv526si.o failed with output:
(Insert Directory stuff here)\ElisXRGame\Library\Bee\artifacts\Android\il2cppOutput\cpp\UnityInterface.cpp(3,10): fatal error: ‘pcl/point_types.h’ file not found
#include <pcl/point_types.h>
1 error generated.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

I have absolutely no clue what this error is. Apparently neither did google. I tried downloading the file it was looking for on the internet (was hoping there was some unity version, but no such luck) and put the file in the given directory. Unfortunately (not surprisingly though) it did not seem to work.
