The parser library code is created in `build/`. To create the full parser code run 
```
make build
````
   

To use the SQL Parser in your own code, you only need to include `SQLParser.h` and build+link all the source files from the parser with your project. See [`hyrise/src/lib/access/sql/SQLQueryParser.cpp`](https://github.com/hyrise/hyrise/blob/master/src/lib/access/sql/SQLQueryParser.cpp) for how it's used in Hyrise.

**Important:** Run tests and add tests for new features.
```
make test
```
