This makes asio link tests pass, accomplishes two things:

* Communicates CMAKE_CXX_COMPILER correctly to subprocess (via
load_cache which may be a bad idea)

* Manually (yuck) pulls the paths of libraries that the link tests
  must link against out of the target properties and passes them to
  the linktest subprocess
