Hopefully I'm misunderstanding you, since otherwise the list would contain close to 4000 files.

But I took a look at Michael Wild's approach (thanks Tyler) which leads me to believe there is no clean way to go about it. I suppose in the spirit of his solution I could create a global list of the archives I obtain, and feed them to target_link_libraries (myexecutable ${my_global_list_of_archives}) in the same scope where I call add_executable().
