OQGRAPH is silently not compiled if boost is missing – configure mentions the fact in passing and proceeds to compile a binary. Instead, ./configure should have failed.

Silent non-compilation of engines and features has been a historic problem for MySQL – the MTR test suite does not detect such omissions and simply skips the relevant tests, which requires extra scripts and work at build time to verify that the binary contains all desired features. Explicit ./configure failures are much easier to detect.
