That is *not* the point. Some people do build tests by default and for
these people, a unit test that doesn't compile means a module that
doesn't compile. Developers that don't build unit tests quite often
introduce compile breakers  for those that do build tests, and that
has to stop.
Technically it might be possible to make (c)make ignore errors
building the test as nothing depends on them. If you think through
what that would lead to you should see that that is also a bad idea.
Basically, those who create problems would not be those who suffer
from them, we'd have even more confusion and so on.
So, sane option: Always build unit tests and fail if they don't build.
