No, my commit removed the test only because it failed with gcc. The issue here is different, this is a CMAKE error that is caused by the CMake change that I did not revert (I did not notice a build bot failing with this CMake error).

@sylvestre, could you share your cmake config/what compilers you are using to help reproducing the issue?

Sure here is the full log

(I am on my phone. This is why it is hard to give you the exact command)
