git clone https://github.com/louishust/xdev-demo.git
cd xdev-demo
git submodule init
git submodule update
mkdir bld
cd bld
cmake ..
make

will got the following error:

/tmp/xdev-demo/third_party/mysql-connector-cpp/common/session.cc:45:10: fatal error: config.h: No such file or directory
 #include "config.h"
          ^~~~~~~~~~

Suggested fix:
the patch is available in attachment

cd xdev-demo/third_party/mysql-connector-cpp

Thanks for the patch. We will use it to fix our build system so that it can be used as a sub-project. Note however, that a typical use scenario we support is to build connector in a separate project, install it somewhere and then use it in your project from that install location (for example define imported lib target in cmake).

Got it

Fixed in 8.0.21.

The CMake configuration files were revised to work better when
Connector/C++ is used as a subproject of application projects. Thanks
to Lou Shuai for the contribution.

This revision does not change the fact that the intended (and
supported) usage scenario is to build the connector in a separate
project, install it somewhere and then use it in application projects
from that installed location (for example, by defining the imported
library target in CMake).
