Thanks!
I'm now using the following snippet to install the *.so on linux and just the
dll on win32. Looks a bit hackish, though.

ADD_LIBRARY(spark SHARED ${LIBSPARK_SOURCES})
...
#We have to use LIBRARY on linux, but that installs the import library on win32
IF(WIN32)
  INSTALL(TARGETS spark RUNTIME DESTINATION ${PRIVATELIBDIR})
ELSE()
  INSTALL(TARGETS spark LIBRARY DESTINATION ${PRIVATELIBDIR})
ENDIF()
