Cool, I'll have a look :)

Yep, make it standard! I hope Krzysztof can chime in, he knows more 
about CMake.

Did you see my cmake code to install to the system-wide python modules 
dir? Have a look at the last lines in the 
/cython-bindings/CMakeScript.txt file. That works for Windows. But 
indeed I think an __init.py__ file is missing. Have a look at the 
py2geom folder.
A modification of this will copy the file:
         INSTALL(FILES "${CMAKE_CURRENT_SOURCE_DIR}/__init__.py" 
DESTINATION "${SITEPACKAGE}/py2geom")

Cheers,
