Putting all the dlls and exes into a single directory is the easiest thing
to do if you don't mind reorganizing your build tree...

If you must keep your build tree, another strategy would be to run all your
tests through a script that drives the test rather than calling the
executable directly. Then, in that script, you could set the PATH env var to
include all the directories where all the dlls are located.
