You have to excluded mytestexe from the ALL target if you do not want
that it gets built by default [1]. (e.g., add EXCLUDE_FROM_ALL to
add_executable [2])

Can't help you there. I usually simply use `make check` to build and run
the full test suite in order to get an overview. Afterwards, I directly
call `ctest` with the desired arguments, for example when triaging a bug.
