The documentation states:

> Compound conditions are evaluated in the following order of precedence: […] Then the boolean operators in the order NOT, AND, and finally OR.

But the following prints “FALSE”:

```auto
cmake_minimum_required(VERSION 3.22)

project(Test)

if(YES OR NO AND NO)
    message("TRUE")
else()
    message("FALSE")
endif()

```

So the expression isn’t being evaluated as `YES OR (NO AND NO)`. Could someone explain this surprising behavior?

Must be a bug, so I’ve opened an [issue](https://gitlab.kitware.com/cmake/cmake/-/issues/23207).
