Sorry for long delay,
I've tried below code (Setting pythonpath environment variable)
and then initialize python interpreter but the embedded python interpreter
did not get the newly assigned PYTHONPATH.
I ve looked at the sys.path in python code (that is run by the embedded
interpreter) and it behaved according to older pythonpath.
Setting environment variable seemed to be correct.
Does py_initialize run in another thread so it starts before setting the
// add custom plib.zip archive to pythonpath
std::cout << "PYTHONPath Set to: " << ::getenv("PYTHONPATH") << std::endl <<
"And Again: ";
