I wonder if we can use the SOURCES property but lift the read-only
restriction by special-casing the property storage similar to how
you do for include directories.  It should know the cmSourceFile*
internally but present the value as a path to the source file
as specified by the project in the property value.  Then replace
the ObjectLibraries member with another representation in the
special SOURCES property storage vector.
