    cmTarget: Fix listing of source files at configure-time. · b8af2011
    Stephen Kelly authored
    Since commit e5da9e51 (cmTarget: Allow any generator expression in
    SOURCES property., 2014-03-18), source files are computed by
    true evaluation of generator expressions, including TARGET_OBJECTS.
    This evaluation requires the presence of cmGeneratorTarget objects
    since commit bf98cc25 (Genex: Evaluate TARGET_OBJECTS as a normal
    expression., 2014-02-26).
    Ensure that we don't attempt to evaluate the TARGET_OBJECTS generator
    expression at configure-time, as can happen if CMP0024 or CMP0026
    are OLD.  Use old-style parsing of the source item to extract
    object target names in that case.
    Avoid calling GetProperty("SOURCES") to bypass warnings from CMP0051.
    Refactor existing logic in GetLanguages which is similar in intent to
    the new GetSourceFiles code.
