In the 2.8.whatever, the following worked without any complaints:

    add_executable (tests/win32_test tests/win32_test.c)

In fact it worked just as I expected to in all ways, including being
about to run

    make tests/win32_test

to make just that executable.

I also discussed this issue on IRC with @ngladitz who suggested the following:

    add_executable (win32_test tests/win32_test.c)
    set_target_properties (win32_test PROPERTIES EXECUTABLE_OUTPUT_PATH tests)

Unfortunately, that does not behave as intended. The win32_test target
ends up in the "." directory instead of the in the "tests/" directory.
