BUG: pylon/pypylon breaks Linux PATH

[mahiuchun]

Describe the issue:

pypylon alters the PATH environment variable and does it in an incorrect way (using ; instead : as separator)

Essential the same issue as https://github.com/basler/pypylon/issues/646

Reproduce the code example:

import os
import pypylon.pylon as pylon

if __name__ == '__main__':
    transport_layer = pylon.TlFactory.GetInstance()
    print(os.popen("echo $PATH").read())
    devices = transport_layer.EnumerateDevices()
    print(os.popen("echo $PATH").read())

Error message:

No response
