[CMake] does cmake get dependencies between asm files? and when said so does it link them?

If it was supposed to work right out of the box without fiddling with
it I'll try to add some more details and a bunch code sample.
All the code involved is part of atmel asf[1]
The 2 files involved are trampoline.x and crt0.x.

crt0.x define _stext

  .global _stext
  .type _stext, @function
_stext:


and trampoline.x uses it

lda.w   pc, _stext

I've a
add_library(crt0 crt0.x)
and a
target_link_libraries(... crt0)

But without some help[2] crt0 doesn't get compiled and linked

[1] I'm working on an older version then the one available on atmel
site but I think you can get the idea

[2]
add_dependencies(trampoline crt0.x)
make it compile
set_property(TARGET SAM3 APPEND PROPERTY LINK_LIBRARIES crt0)
make it link
