Steve, I think this is a parsing problem here:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmTargetLinkLibrariesCommand.cxx;hb=v2.8.12#l151
 http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmTargetLinkLibrariesCommand.cxx;hb=v2.8.12#l181

It should allow LINK_PUBLIC to occur after another LINK_PUBLIC,
and LINK_PRIVATE to occur after another LINK_PRIVATE.  Currently
it requires that they alternate.  Thew newer PUBLIC/PRIVATE/INTERFACE
options allow any order and repeats.

Thanks,
