[CMake] Tag Variable <OBJECTS>

[Matthias Goesswein]

Hello!

My libarian-tool needs a flag before each object file:

e.g.

libarian -a file1.o -a file2.o -a file3.o library.a

CMake provides the <OBJECTS> tag variable for use within the rule 
variable of the libarian, but i didn't fond a way to insert the "-a" 
flags before each object file.

Is there any way for doing that?

Cheers,
Matthias.
