Visual Studio CMake 在包含许多项目的克隆仓库上

Question

I have a git repo with many many projects in it. I am trying to use MSVC with Clang-cl and CMake, Git.

I started out building a project directly in MSVC:

CMakePresets.json
CMakeLists.txt
asource.file.cpp

When I was happy with the working code, I moved these files into /repo/subfolder, and committed them.

Now I am cloning my repo as a new project: I chose to "clone repository" at MSVC project creation, and I want to avoid building the /repo root CMake project. Instead I want to build the /repo/subfolder CMake project. How can I achieve this?

Imagine I am on the Linux command line. Instead of:

cd myrepo
mkdir -p build && pushd build
cmake .. -G Ninja

I want to:

cd myrepo/subfolder
mkdir -p build && pushd build
cmake .. -G Ninja

The difference is that I want to make use of a CMake project in a subfolder instead of the root folder. I have been unable to build anything but the root project.

I've tried:

1. Right-click CMakeLists.txt and Configure CMake - it configures the top-level CMake project instead of the file I am clicking on.
2. Right-click CMakePresets.json and click all the "Add..." etc. there. It seems to edit the presets file itself.

I could not figure out how to have many CMake builds in one project cloned from a repo, but I figured out how to open any folder as its own CMake project:

File -> Open -> CMake...

Select the subfolder as your project. Then MSVC will trample your CMakePresets.json (truncating it to 0 bytes) which you can reset with Git -> Undo Changes. Once you have undone the changes you will want to reset the CMake cache and reconfigure in order to avoid failed CMake compilation tests.

And now it should work. Unfortunately it doesn't seem to be very easy to clone a repo and then work with $project inside it.
