RUN_TESTS target has no dependencies on the programs it runs

[MarkCallow]

So the tests often fail because the executables aren't found as they haven't been built. It must have dependencies on all programs it is testing.

@atteneder please take a look at this and #281 urgently. Both are costing me a lot of wasted time.

Unfortunately this is a known flaw in CMake without a proper solution: https://gitlab.kitware.com/cmake/cmake/-/issues/8774

To avoid missing exes, I suggest:

1. Run the ALL_BUILD target before running tests
2. Create a custom target with dependencies on all test executables and run this target before running tests

Let me know if you think option 2 is in any way useful/an improvement, in which case I'll make a PR.

Otherwise there's nothing left to do other than upvoting/commenting the original issue.

[MarkCallow]

Running ALL_BUILD works. Is there some advantage to a custom target that I'm missing? I don't see any benefit over ALL_BUILD.

I've upvoted the CMake issue. I'll leave this open to document the problem and hopefully stem a tide of duplicate reports.

[atteneder]

Only advantage is, it would build only the executables required for testing and not other things (like the loadtest apps). Downside: CMake config/Xcode project getting a bit more bloated.

Ping @atteneder. This still bites me regularly when I forget to first build "package". Please try to fix it.
