Thanks for your interest in this project, part of the Eclipse C/C++ Development Tools project
The source code can be found in the following repository: https://github.com/eclipse-cdt/cdt-gdb-adapter
This is an implementation of the Debug Adapter Protocol for gdb. It is loosely based on the Eclipse CDT MI layer. We are at least learning from it.
See build instructions in the Readme and details on testing in the test readme. Further information on building, including CI information, download locations, etc can be found in the Wiki
