AFAIK you are the first one that tries to compile the python bindings on
Windows. So it does not suprise me that it does not work out of the box.

Can you tell us which version of cmake you are using? And which version of
Orocos KDL?

After looking at the *-config.cmake files it appears we are not setting
*_FOUND at all. But according to this page
http://www.cmake.org/Wiki/CMake/Tutorials/How_to_create_a_ProjectConfig....
that should not be necessary.

Could you post the original contents of the following variables:

orocos_kdl_INCLUDE_DIRS

This looks like you are using an older version of KDL (not master) since
currently the above variables are not used instead we have

orocos_kdl_INCLUDE_DIRS
orocos_kdl_LIBRARIES
