Summary:                    target_link_library may have option not to add
dependencies, for archive target.
Description: 
  add_library(foo_lib ...)
  target_link_libraries(foo_lib bar_lib)

I understand it implies add_dependencies(foo_lib bar_lib).

In practice, foo_lib doesn't always require that bar_lib were up-to-date.
In other words, foo_lib and bar_lib might be built in parallel.
This issue makes parallel build too serialized and slow.

Even if lib(s) were split with objlib, archiver(ar cr) is serialized.
(When I tried, both objlib(s) can be built in parallel.)

Of course, 

  add_library(foobar_so SHARED ...)
  target_link_libraries(foobar_so foo_lib)

I think it'd be reasonable to imply add_dependencies(foobar_so foo_lib bar_lib)
for foobar_so.
