I always use the $<TARGET_FILE> generator expression in add_test(). It
makes the code more robust:
When someone changes the target name (or when there is a typo), the
generator expression cannot be evaluated and an error is reported at
configure time.
When the target name is used without a generator expression, typos can
lead to strange testing results.
