[CMake] fixup_bundle, shared libs and Plugins

[Michael Jackson]

And just to follow up a bit with something else, I added the following bit of cmake code for the 2 libraries MXADataModel and AIMLib:

SET_TARGET_PROPERTIES(${targetName}
   PROPERTIES
   LINK_FLAGS "-current_version ${${CMP_PROJECT_NAME}_VERSION} -compatibility_version ${${CMP_PROJECT_NAME}_VERSION}"
   INSTALL_NAME_DIR "${CMAKE_INSTALL_PREFIX}/lib"
    BUILD_WITH_INSTALL_RPATH 1
 )  

And now I can get everything to work. This seems like an odd thing to have to add. Why can't fixup_bundle() resolve an item that is in the build tree? Seems that I have to install the library FIRST to an external location with the proper install_name for that location then run my fixup_bundle(). I can't see the difference.
