You could also use the ${CMAKE_STATIC_LIBRARY_PREFIX}, 
${CMAKE_STATIC_LIBRARY_SUFFIX}, ${CMAKE_SHARED_LIBRARY_PREFIX} and 
${CMAKE_SHARED_LIBRARY_SUFFIX} cmake variables to construct the filename:

set_target_properties(mylib PROPERTIES
    IMPORTED_LOCATION 
${CPPLIB_DIR}/${CMAKE_SHARED_LIBRARY_PREFIX}mylib${CMAKE_SHARED_LIBRARY_SUFFIX})
