Also quick workaround for Intel on Windows, it needs DLLs in the gemini.bin directory, having the DLLs in PATH didn't help. This can conflict with Python however for ctest.

To give better visibility to skipped tests, use DISABLED test property so they show up in test list, not just silently ignored.

For the moment, Meson is disabled as CMake >= 3.15 did what we originally needed Meson for.
