VS solutions/projects in the ports folder pollute VS targets list

[Trider12]

Describe the bug
When using vcpkg as a submodule, various .sln and .vcxproj files located in the vcpkg/ports/ directory pollute the targets list of Visual Studio:

Environment

• OS: Windows
• IDE: VS2022

To Reproduce
Steps to reproduce the behavior:

1. Create a CMake project (not sure whether the same problem occurs with VS projects)
2. Have vcpkg cloned somewhere inside the project directory

Expected behavior

• Solution 1: remove these types of files from vcpkg
• Solution 2: some way to tell VS to ignore the vcpkg folder

Additional context
The Show/Hide Debug Targets feature is helpful, but requires to manually select every target imported by vcpkg and is reset when VS project cache is deleted.

The same problem occurs in the Solution Explorer window, but there's no filtering functionality there:

Are there some steps to reproduce? May I ask how you use vcpkg in cmake?

You don't even need to "use" vcpkg to observe this issue. Just have vcpkg cloned inside a CMake project folder and then open that project in VS.

I did this, but sorry I didn't reproduce your issue. After the build, there are only original files in the ports/ directory, without .sln and .vcxproj.

I didn't mean the ports/ directory literally. I meant that ports inside that directory have these files. Just open the targets list like in the screenshot I provided.

winpcap: #5478
sdl1-mixer: #30921

Confirmed, I will follow #31685 to fix it to avoid them being detected by VS.
