sqlpp overwrites the output file without regard to its contents. Ensure that the output file name does not match the name
of any of your source files. By default, sqlpp constructs the output file name by changing the suffix of your source file
to .cpp. When in doubt, specify the output file name explicitly, following the name of the source file.
Compile each C++ source file for the target platform of your choice. Include:
each C++ file generated by the SQL preprocessor
any additional C or C++ source files required by your application
Link all these object files, together with the UltraLite runtime library.
