Building a C++ project with MinGW using Visual Studio Code
In CMake Tools extension settings I specified my CMake path:
and built my project with MSVC 2022 first and then switched to MinGW.
Building a project with MSVC 2022
On my machine with installed MSVC 2022 it automatically generated configuration file %LocalAppData%/CMakeTools/cmake-tools-kits.json:
