Win32 LoadLibrary searches system directories, the executable's
directory, the current directory, and finally PATH. It's simple to
update the PATH environment variable for the current process:
os.environ['PATH'] = ';'.join([absolute_lib_path, os.environ['PATH']])
You can also call kernel32.SetDllDirectoryW(absolute_lib_path) to
insert a path to be searched immediately after the executable's
directory. Afterward call kernel32.SetDllDirectoryW(None) to restore
the normal safe search order.

I extracted the debs:
dpkg-deb -x <deb> <directory>
Then I copied the required .so files to the lin32 directory and
created the symbolic links with "ln".

The Debian repo has ICU 4.8 (libicu48). It also has libstdc++5. I'm
sure the same applies to other Linux distros. That leaves only Intel's
C++ libraries to be installed: libimf.so, libirc.so, and
libcxaguard.so.5. I think Intel's license allows you to redistribute
these with an application. Anything less would be unreasonable. But...
Actually, the fact the lin32 and lin64 versions in your repo were
linked to different versions of ICU made me suspicious. I decided to
downloaded "IO_Module_for_SPSS_Statistics_21001.zip" (version 21) to
get the lin32 directory from the source. Turns out this version
doesn't depend on Intel's libs at all, and it's linked to the ICU 4.8
libs and libstdc++.so.6. It does add libzlib123spss.so, but that's
simple to preload.
In fact, if you'd rather not tinker with PATH on Windows, or install
libraries to the system, or patch the ELF runpath -- then you could
simply load the required libraries manually in the following sequence
(version 21):
Linux Windows
