error: undefined reference to 'CppSQLite3DB::~CppSQLite3DB()'

I use CppSqlite3 from neosmart: https://github.com/neosmart/CppSQLite, with cmake, but I run into errors like
error: undefined reference to ‘CppSQLite3DB :: ~ CppSQLite3DB ()’

Why not ask them for support? We don’t own/write/use this in our products.
