No tests were run.

Start by reproducing `make test` with `/opt/lampp/bin/php` and inspect the reported failure while loading `ui.so`. Trace the `libcairo.so.2` and FreeType dependency versions involved in the undefined symbol error. Done means the extension loads without the startup warning and the test command runs its tests.
