Issues with testing

When running cmake without disabling testing, I get some strange timeout problems:
```

I added googletest using spack (version 1.12.1). I then disabled testing in cmake, and it compiled.

No urgency from me to find the root cause, I don't need testing - I just thought to make you aware of this :)

It might be nicer if the default would be to disable tests, which also reduces dependencies - since as a user this is probably not required(?)

Start by reproducing the CMake build with testing enabled and inspect GoogleTest discovery for tests/unit_tests/c++/test_profiler, test_hashtiming, test_regionname, and test_hashtable. Determine why discovery times out and whether the intended outcome is fixing that failure or changing the default testing configuration; completion should include a reproducible validation of the chosen behavior.
