| ------- |
| |
| ``$<IN_LIST:...>`` handles empty list items. |
| |
| In CMake 3.13 and lower, the ``$<IN_LIST:...>`` generator expression always |
| returned ``0`` if the first argument was empty, even if the list contained an |
| empty item. This behavior is inconsistent with the ``IN_LIST`` behavior of |
| :command:`if`, which this generator expression is meant to emulate. CMake 3.14 |
| and later handles this case correctly. |
| |
| The ``OLD`` behavior of this policy is for ``$<IN_LIST:...>`` to always return |
| ``0`` if the first argument is empty. The ``NEW`` behavior is to return ``1`` |
| if the first argument is empty and the list contains an empty item. |
| |
| This policy was introduced in CMake version 3.14. 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. |
