Description:
When compiling version 1.1.7 of the MySQL Connector/C++ against a MySQL C API prior to 5.7, the compilation fails due to the reference to MYSQL_TYPE_JSON.
How to repeat:
(Assuming that mysql_config -fno-rtti patch has already been applied)
On Ubuntu 15.04:
~/mysql-connector-cpp$ sudo apt-get install -y libmysqlclient-dev
~/mysql-connector-cpp$ cmake .
~/mysql-connector-cpp$ make

Suggested fix:
This can be fixed by checking for the MYSQL_TYPE_JSON at compile time and optionally including those switch/case conditionals only if detected in the underlying C API.
