[CMake] Can you add sources to a target library after add_library()?

Personnally I sometime use several variable like:

add_library(blah
                 ${BLAH_SOURCE}
                 ${BLAH_SOURCE_OPT1}
                 ${BLAH_SOURCE_OPT2}
                 ${BLAH_SOURCE_OPT3})

xxx_OPTy var may contains source or may be void and off course
should be defined BEFORE add_library is called.

It is mostly like conditionnally adding the same content to a list but
may required less conditionnal because xxx_OPTy may defaulted to void content.

Would you explain us why you need to add source AFTER add_library
and may be why conditionnal is awkward?
