# Due to the CONF_ENV options, libpython-dir must be set manually
# or else the error: "Python dynamic library path could not be determined"
# occurs. We set the libpython-dir to /usr/lib as this path is hard-coded
# into the resulting .so file as /usr/lib/python3.$(PYTHON3_VERSION_MAJOR).so.
# Because we provide PYTHONPATH=$(PYTHON3_PATH) above, the logic in the meson
# file uses the above python path to determine if /usr/lib/ has the proper .so
# file. Because Buildroot provides the appropriate paths, the meson file finds
# the correct .so file, and the resulting compiled library has the appropriate
# path of /usr/lib/python3.$(PYTHON3_VERSION_MAJOR).so
