sorry for taking so much time for this wimpy problem. I think I found the issue and it's simple as always.
See some small comments inline

Yes, it did not show up, but run without a warning, because a directory (and thus product) test existed :/

I tried this with success :) Thanks for the interesting build script!

Not for me - renaming didn't solve it

Instead I moved ENABLE_TESTING() from test/CMakeListst.txt to my root CMakeLists.txt
I think this is not stated in the documentation.
