It would be really nice to have a switch to omit building the tests for the dependencies. For e.g. kate build time would be ca. 50%.
Try setting the `run-tests` option to 0 (or false) as a global setting, and then if you want to run tests for the specific module you are interested in, you can set `run-tests` to `true` for that module specifically. See also https://docs.kde.org/trunk5/en/extragear-utils/kdesrc-build/conf-options-table.html#conf-run-tests You would need to rebuild the affected modules using at least the --reconfigure commandline argument to kdesrc-build (so that CMake is re-run), but if that doesn't work then please reopen as that would then be a bug instead of a feature request ;).
