Thanks for making the video. It indeed looks like the linker gets stuck and doesn’t exit even after you terminate it with Ctrl-C.
The linking is normally performed by your toolchain that is in turn invoked by CMake and unfortunately there’s not much VisualGDB can do about it. Please try building the project manually outside VisualGDB. If you observe different behavior, please let us know and we will help you narrow down the differences between the setup used by VisualGDB and the manual setup.
If the linking still gets stuck, please try using a different toolchain or experiment with the exact linker inputs in order to work around it (e.g. regroup the code into several static/dynamic libraries).
