Repro steps:

1. Open VScode
2. Create a new folder named 'Test' and open it with vscode.
3. Create a file named CMakeLists.txt under test with the following content:

   cmake_minimum_required (VERSION 3.8) 
   project ("test") 
   add_executable (test "test.cpp" ) 

4. Create a file named test.cpp under test with the following content:

   #include <iostream> 
   int main(int argc, char **argv) 
   { 
   std::cout << "Hello World" << std::endl; 
   return 0; 
   } 

5. Create "CMakePresets.json" file and copy the following code into the file, then save it

   {
   "version": 3,
   "configurePresets": [
   {
   "name": "windows-base",
   "hidden": true,
   "generator": "Ninja",
   "binaryDir": "${sourceDir}/out/build/${presetName}",
   "installDir": "${sourceDir}/out/install/${presetName}",
   "cacheVariables": {
   "CMAKE_C_COMPILER": "cl.exe",
   "CMAKE_CXX_COMPILER": "cl.exe"
   },
   "condition": {
