| CMP0077 |
| ------- |
| |
| :command:`option` honors normal variables. |
| |
| The ``OLD`` behavior for this policy is to clear any existing normal variables |
| with the same name. The ``NEW`` behavior for this policy is to not create |
| a cache entry or modify any existing normal variables if a normal variable |
| with the same name already exists. |
| |
| This policy was introduced in CMake version 3.13. CMake version |
| |release| warns when the policy is not set and uses ``OLD`` behavior. |
| Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` |
| explicitly. |
