[CMake] add_test to support generator expressions?

[Chris Green]

Hi,

I have a function cet_test(), which allows a user to specify the details 
of a test which will be executed via a wrapper, cet_exec_test. It calls 
the CMake add_test() macro to set this up. The user may subsequently set 
the SKIP_RETURN_CODE property on this test, which must be communicated 
to cet_exec_test() so that it can notify CMake if the test requirements 
are violated. I attempted to do this with:

add_test(NAME ${target}
	 ...
	 COMMAND cet_exec_test ... --skip-return-code $<TARGET_PROPERTY:${target},SKIP_RETURN_CODE>
	 ...)

but this resulted in an error. Am I using generator expressions wrongly 
in this case, or does add_test() not support them? Is there something 
else I can do?

Thanks for any help,

Chris.
