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)
