make errors on Mac

[kanzha2020]

Hello!
I am trying to get this project up and running on my Mac (macOS Monterey 12.6).

• Installation of point cloud library seems correct.

• I was able to run cmake .. successfully in the build folder.

• However, I got errors when typing make in the build folder. Does anyone has an idea what might be the problem? Thanks a lot!
