Sometimes when I run a CMake project, an error is reported: “Severity Code Description Project File Line Suppression State”  
Error: cmake version 3.26.4-msvc4  
“Sometimes, deleting and regenerating the ‘out’ directory resolves the error. However, there are times when even after deleting the ‘out’ directory, the error persists.”
