ImportError: libpango_windowing.so: cannot open shared object file: No such file or directory

I'm using Ubuntu 22.04 with CUDA 12.4 and CuDNN 8.9.7

I've tried local build first, then the Docker image. Everything goes fine without any errors. When I run python demo.py --imagedir=movies/IMG_0492.MOV --calib=calib/iphone.txt --stride=5 --plot --viz I get:

ImportError: libpango_windowing.so: cannot open shared object file: No such file or directory

Which is strange, because I've built and ran sudo make install for Pangolin, and /usr/local/lib/libpango_windowing.so exists. Where is the issue stemming from?
