Yes it uses the modified FindKDE4.cmake  and KDE4_DATA_DIR is set
the problem is that  KDELibsDependencies.cmake uses
${KDE4_INSTALL_DIR} that is retrieved from this code
get_filename_component(_DIR ${KDE4_KDECONFIG_EXECUTABLE} PATH )
get_filename_component(KDE4_INSTALL_DIR ${_DIR} PATH )
but KDE4_KDECONFIG_EXECUTABLE is setted to the linux one, if i set it
to the windows one it goes ahead and it find include and library dir
but it doesn't find kde4automoc and kconfig_compiler
-- Found KDE 4.1 include dir: /windows/kde4/include
-- Found KDE 4.1 library dir: /windows/kde4/lib
-- Didn't find the KDE4 kconfig_compiler preprocessor
-- Didn't find the KDE4 automoc

Yes it works, I used the cache file just to disable gssapi
