How to pass quoted parameters to add_test in cmake?

Question

I'm trying to pass parameters to a gtest test suite from cmake:

add_test(NAME craft_test
         COMMAND craft --gtest_output='xml:report.xml')

The issue is that these parameters are being passed surrounded by quotes, why? It looks like a bug, is there a good way for avoiding it?

$ ctest -V

It's not the quotes that CMake adds that is the problem here; it's the single quotes in 'xml:report.xml' that are at fault.

You should do:

add_test(NAME craft_test
     COMMAND craft --gtest_output=xml:report.xml)

This does the trick, although when running the test outside ctest I passed args with the single or double quotes and it worked ok (as can be checked here and here. I'm afraid I may stumble on such quoting problem when I'm required to use them for some reason. – Honora

I agree that the quotes escaping is a bit of a pain in CMake, but I think in this case you should be OK. The only reason I can see you'd need quotes there is if your filename or path had spaces, and then you can do COMMAND craft "--gtest_output=xml:rep ort.xml" I think. – Sign
