| .. versionadded:: 3.30 | |
| :command:`enable_language` must not be called before :command:`project`. | |
| In CMake 3.29 and below, if a project called :command:`enable_language` | |
| before the first call to :command:`project`, the language would be enabled | |
| but possibly using unset details that were expected to be set. | |
| In CMake 3.30 and above, :command:`enable_language` prefers to reject this | |
| case and stop with a fatal error instead if it detects that :command:`project` | |
| has not yet been called. This policy provides compatibility for projects that | |
| happened to work when :command:`enable_language` was called before | |
| :command:`project` and have not been updated to call these commands in the | |
| required order. | |
| The ``OLD`` behavior for this policy is to allow :command:`enable_language` | |
| to be called before :command:`project`. The ``NEW`` behavior for this policy | |
| is to fail with a fatal error in such cases. | |
