The easiest thing to do is look at one of the build directories for just
about any OOT module - and see how it's done.

The enclosed example script is from gr-lte OOT module.

Note that the

  ./gr-lte/build/swig

directory is in the script's PYTHONPATH, the

  ./gr-lte/build/python

directory is in the script's PATH, and the

  ./gr-lte/build/lib

directory is in the script's LD_LIBRARY_PATH.
