Thanks Jean-Christophe. So I guess the short answer is "ctest can't do this".

It seems they have made significant modifications to CxxTest so that
the bin/cxxtestgen that ships with CxxTest is no longer required
(they've replaced it with C macros). I like the BTK way better :)

I guess I'm not sure what the advantage of using CTest along with
something like CxxTest is. If you build an executable using CMake,
then why not just run ./MyTests from the terminal instead of making an
interface so that you can call 'ctest'. CTest will report a single
pass or fail, because as far as it is concerned there is only one
test, right? The relevant file is
https://code.google.com/p/b-tk/source/browse/BTK/trunk/Testing/Code/CMakeLists.txt
that only has one add_test call.

Any thoughts?
