I am curious as well about that issue.  It is possible the error he is getting
is because one or more of his tests are not working because he doesn't
use a build step to build something in his project that is needed by those tests.

So to ask the question directly to the OP, do you have any CMake logic
anywhere in this project that builds software, e.g., the add_library or
add_executable commands?  If so, you do have to build all such software
first (by building the "all" target) before you run ctest if any
of your ctest tests depend on those built libraries or executables.
