CMake created VS solution foldername conflicts with project/solution name

### Issue Description

If your cmake has `set_target_properties(${PROJECT_NAME} PROPERTIES FOLDER "{NAME}")` line, it creates a project folder in the solution list. However, the folder name must not be the same as any project's or solution's name. Otherwise it will cause ` Solution file error MSB5004: The solution file has two projects named "xxxx"`. For example your solution is named "GoodWork.sln", and in your cmake script, you have `set_target_properties(${PROJECT_NAME} PROPERTIES FOLDER "GoodWork/Test")` in any of the CMakeLists.txt, you will see this error.

### Expected Behavior
Build correctly.

### Actual Behavior

Error Solution file error MSB5004: The solution file has two projects named "xxxx"

### Analysis
It won't be a problem if you open the solution with VS and build it there. This project only occur using MSBuild in command line. So that factors out the issue from cmake.
