How to avoid stepping into internal stl implementation when pressing F11 (step into)

[onecable5781]

I am on Windows/CMake and call cl.exe and ninja for build.

I have the following code on Windows and I am trying to step through the code using VSCode cpptools extension and invoke cl.exe via CMake followed by a ninja.exe build.

#include <iostream>
#include <vector>

void print(int *arr, int size)
{
    for (int i = 0; i < size; i++) {
        std::cout << arr[i] << std::endl;
    }
}

int main()
{
    std::vector<int> v = {1, 2, 3, 4, 5};
    print(v.data(), v.size());//Line where breakpoint is set
    return 0;
}

Here, with the breakpoint set at the print call in main, hitting F11 takes me to the following line

    _NODISCARD _CONSTEXPR20 size_type size() const noexcept {
        auto& _My_data = _Mypair._Myval2;
        return static_cast<size_type>(_My_data._Mylast - _My_data._Myfirst);
    }

inside of C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.42.34433\include\vector

I would like to avoid having to step through such internal code and directly step into my user-written print function.

Interestingly, debug running this code and pressing F11 using Visual Studio .sln/.vcxproj native Visual Studio project/solution files does not go into the internal vector implementation. Opening the project inside of Visual Studio as a CMake project also does not take me into the internal vector implementation. I end up inside of the vector implementation only on using VSCode.

Is there a way to fix this issue?

This happens even when I try to compile the code with /JMC flag (Reference to Just My Code Debugging https://learn.microsoft.com/en-us/cpp/build/reference/jmc?view=msvc-170).

My compile_commands.json is:

"command": "C:\\PROGRA~1\\MICROS~4\\2022\\COMMUN~1\\VC\\Tools\\MSVC\\1442~1.344\\bin\\Hostx64\\x64\\cl.exe  /nologo /TP -external:W0 /DWIN32 /D_WINDOWS /EHsc /Zi /Ob0 /Od /RTC1 -std:c++17 -MDd /ZI /JMC /W3 -openmp /FoCMakeFiles\\CMakeProject.dir\\code\\main.cpp.obj /FdCMakeFiles\\CMakeProject.dir\\ /FS -c C:\\TestsDoneByMe\\step_into_stl_code\\code\\main.cpp"

My CMake task inside of tasks.json which invokes the configure/compile/build are:

"command": "cmake -G\"Ninja\" -S . -B ./cmake/windows/dbg -DCMAKE_BUILD_TYPE=Debug; cmake --build ./cmake/windows/dbg --config Debug"
