In 2.6.4 (where we are now) it used Makefiles and we patched the Makefiles to not run the tests.

3.x moves to Meson, so the patch is no longer useful.  But we need an analogous patch to fix this:

Looking at the files:

https://github.com/isc-projects/kea/blob/master/meson.build#L304-L309

https://github.com/isc-projects/kea/blob/master/src/lib/config_backend/tests/meson.build#L1-L3

it’s not clear to me why it’s trying to run the tests.
