| Verify interface header sets checks executables without exports. |
| |
| When :prop_tgt:`VERIFY_INTERFACE_HEADER_SETS` is set to true on an executable |
| target, CMake 4.2 and below would only perform those checks if the target's |
| :prop_tgt:`ENABLE_EXPORTS` property was true. The reasoning behind this |
| exclusion was that no other target could consume the headers of an executable |
| target if that executable target didn't export symbols. Since then, other |
| use cases have emerged for verifying header file sets where exporting symbols |
| is no longer a requirement. Therefore, CMake 4.3 and above prefer to verify |
| interface file sets of executable targets regardless of whether they export |
| symbols or not. |
| |
| The ``OLD`` behavior of this policy only verifies interface file sets of an |
| executable target if its :prop_tgt:`ENABLE_EXPORTS` property is set to true. |
| The ``NEW`` behavior always verifies interface file sets of an executable |
| target when :prop_tgt:`VERIFY_INTERFACE_HEADER_SETS` is set to true. |
