Okay... that makes sense.  But... since I have the link line with
VERBOSE=1, I know advapi32 is the last library...

CMake Error at eltanin/sdlgui/src/eltanin_sdl/CMakeLists.txt:68
(target_link_libraries):
  Cannot specify link libraries for target "advapi32" which is not built by
  this project.

... or I know the last library that I did build...

CMake Error at eltanin/sdlgui/src/eltanin_sdl/CMakeLists.txt:68
(target_link_libraries):
  Attempt to add link library "eltanin_sdl_deadstart_end" to target
  "playcard" which is not built in this directory.

... so I can put it in the playcard target, and reference the library,
and it gets put in a good place.

Is there something I can do to make sure this specific library is
last?  That maybe someone needs to update the cmake scripts?

It's possible with time that this will no longer be the last library....

Where would I put the libraries then? as part of the sources?
