gr-display "import display" causes error

I have installed gr-display and added it to my flowgraph. When I run the flowgraph I get the following:

 

Traceback (most recent call last):

  File "/home/wa4ywm/Softrock/Softrock_FT8.py", line 26, in <module>

    import display

  File "/usr/local/lib/python3.11/dist-packages/display/__init__.py", line 22, in <module>

    from .display_python import *

ImportError: libgnuradio-display.so.3.10.0: cannot open shared object file: No such file or directory

 

Note that when I performed the build I used the instructions in the README file. The "cmake –DCMAKE_INSTALL_PREFIX = " failed. So I used cmake ../ to build the OOT.

 

Thanks for any help.
