Application Cannot Open Files Specific to its use

I am trying to use the VTK example "SimplePointsReader", which has built and
produces the application file.  However, when the application is run in the
terminal window, the error message "The document 'simple.xyz' could not be
opened.  SimplePointReader cannot open files of this type." (screenshot). 
This also happens with "PNGReader", same error, but with PNGReader instead
of SimplePointReader, and "PNG files" instead of just 'files'.  Why am I
unable to view these files within the application?

Thanks,
Austin

I am using the most recent version of VTK and Xcode, and Mac software
version 10.14.3.
