[CMake] Can't run Cocoa test application in CTest

[Tron Thomas]

I tried that originally, and it does not work.  When add_executable is 
used to create an application bundle on MacOS X, it does not simple 
build an executable program.  It creates an entire directory structure 
that bundles up the exectuable.  CTest does not seem to understand how 
to deal with this bundle; it expects a runnable executable as the name 
for the second argument to add_test.
