how to debug SEAL in VS Code?

[friendsAI]

I set breakpoints in _bgv_basics.cpp, and execute these commands in console window: cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug, cmake --build build, and in VS code, I click "run-->start debugging" , but it can't enter degbug mode, it reports "Module containing this breakpoint has not yet loaded or the breakpoint address could not be obtained." .
