@nico @jhasse @digit-google I know you all must be very busy, sorry to be impatient on this one, but this is just 1 line that fixes the CI test. Can we do it?

My other PR's CI test states:

Run ctest -C Release -vv
CMake Error: Unknown argument: -vv
CMake Error: Run 'ctest --help' for all supported options.

a similar fix is part of #2041

Correct--for most of CMake's history, CTest would ignore invalid flags, which was quite confusing. As in this case, where "-vv" did nothing, but now to help avoid confusion, CTest errors on invalid command line flags.

I would prefer a version which avoids ctest all together. Not sure what the advantages of it are besides issue likes this.

There were other issues with ctest in the past and my general opinion of it is, that it should be avoided at all costs and nuked from existence.

@jhasse ok. no more ctest

I'm not going to bother changing the title of the PR, if that's ok...

@jhasse I dug deeper and found out that --config is only for multi-config generators

When ctest was used with the "Xcode" generator, it should have been used directly in the subdirectory without a -C option

for context

nevermind after reading more documentation I see it is considered a multi-config generator even though many people do not use it that way.

so now, just correcting the path

Thank you for this, I am glad we can get rid of CTest too. @jhasse, can we submit this asap to unblock all other PRs that fail their checks because of this issue?

Thanks!
