# PyPylon is a tricky library to bundle. It encapsulates the pylon C++ SDK inside
|
# it with modified library references to make the module relocatable.
|
# PyInstaller is able to find those libraries and preserve the linkage for almost
|
# all of them. However - there is an additional linking step happening at runtime,
|
# when the library is creating the transport layer for the camera. This linking
|
# will fail with the library files modified by pyinstaller.
|
# As the module is already relocatable, we circumvent this issue by bundling
|
# pypylon as-is - for pyinstaller we treat the shared library files as just data.
