It seems to be copying the required library OK, but something is going
wrong when it tries to load it. I'd hazard a guess that Cython's module
initialisation is interacting with cx_Freeze's extension module loader
code. But I don't know what Cython could be doing.
Some background on what cx_Freeze is doing: packages are stored in a zip
file, from which only Python modules can be loaded, not extension modules.
So, when it freezes an extension module, it copies the library (.so/.pyd)
into the build directory, and creates a Python shim module at the correct
point in the package, which will load the extension module when it is
itself imported. The source for that shim is here:
https://bitbucket.org/anthony_tuininga/cx_freeze/src/3b056cee2d76f8f6c004e0cf8c38cfba91c66f21/cx_Freeze/freezer.py?at=default#cl-22
I guess now you'll need to work out what Cython module initialisation does,
and how it might be interacting with that.
