lgtm. The code is a bit rough, but the result is exactly what we wanted:

---8<---
Requested Spotlight support, checking for bison
Checking for program bison                         : /usr/bin/bison 
Using bison version                                : bison (GNU Bison) 3.0.4 
Requested Spotlight support, checking for flex
Checking for program flex                          : /usr/bin/flex 
Using flex version                                 : flex 2.6.0 
Checking for tracker-sparql-1.0                    : yes 
---8<---
