Can't use/create Debug Config for OSS-7 Stack
OSS-7 is the open-source stack for the DASH7 protocol:
https://mosaic-lopow.github.io/dash7-ap-open-source-stack/
The build system is created with CMake:
https://mosaic-lopow.github.io/dash7-ap-open-source-stack/docs/building/
Specifying -G "Eclipse CDT4 - MinGW Makefiles" on the CMake command line completes without complaining, and does create the expected Eclipse .project and .cproject files.
STM32 Cube IDE happily opens these, and builds successfully.
But I can't seem to create a Debug configuration that works - the 'Debug' button always remains greyed-out - even after pressing 'Apply' on any changes:



So what's going wrong?
Why can't I use this Debug Configuration?
What is keeping the 'Debug' button disabled?
The Target is a B-L072Z-LRWAN1, it is connected and a 'Scan' on the 'Debug' tab will read its serial number.
