You are right there is no "functional" difference,
in one case you'll have
make test --> ctest --> ctest
and in the other
ctest --> ctest

Then this executable should be built with add_executable somehow
add_test macro does not compile anything, that's may be were you
have missed something.

add_test(testname Exename arg1 arg2 ...)

Exename should exists: either as an add_executable target or because
it's a sripts etc....
CTest won't BUILD Exename even if there is Exename.cpp in the
appropriate directory.

I think (but I may be wrong too) that you supposed may build needed executable
from source of the same name. This is not the case, CTest is **only**
executing some prebuilt executable with given agrument.

I did know that, I did cut in order to minimize the mail size.
I was trying to show you that your single call to ctest is generating
a recursive call.
