We should add this question to the faq :)
On win32 we need something more. kde4_add_library(foo ...) creates a symbol  \
MAKE_FOO_LIB. This symbol is needed to define proper exports for the library on \
win32:

#ifdef _WIN32
# ifdef MAKE_FOO_LIB
#  define FOO_EXPORT KDE_EXPORT
# else
#  define FOO_EXPORT KDE_IMPORT
# endif
#else
# define FOO_EXPORT KDE_EXPORT
#endif

You have to do this for every lib you want to export symbols from.
