I think your best solution here might be to just set sys.path yourself
(https://docs.python.org/2/c-api/sys.html#c.PySys_SetPath) just after Py_In=
itialize, overwriting the default values. This also gives you the added be=
nefit of being able to put the Python libraries (Lib/**.py and PCbuild/*.py=
d) wherever you want them (even in the same folder, or even a zipfile), rat=
her than trying to fit them into where Python expects them to be, and you d=
on't run the risk of running Python code that really probably shouldn't hav=
e been findable anyway.

Hope this is of some help,
