[CMake] Best way to write add_test that depends on shared objects

The alternative is to generate scripts that set the path: since you're 
apparently on Windows, the standard RPATH support on Linux won't help 
you.  You'll want to configure_file scripts that effectively do this:

set PATH=@PATH_TO_SHARED_LIBRARY@;%PATH%
@YOUREXE@

In fact, if you wanted it to be super general, you could do this:
set PATH=@PATH_TO_SHARED_LIBRARY@;%PATH%
%*

in "launcher.cmd" for example, then call
launcher.cmd yourexe

Hope this helps!
