Usually if you use TARGET_LINK_LIBRARIES, CMake will handle the dependencies
automatically

ADD_LIBRARY(portlib ${portlib_srcs} ${portlib_public_hdrs})
IF(WIN32)
   TARGET_LINK_LIBRARIES(portlib ws2_32)
ENDIF()


ADD_EXECUTABLE(foo foo.cc)
TARGET_LINK_LIBRARIES(foo portlib) # on WIN32, will be linked against ws2_32
as well
