| VERIFY_INTERFACE_HEADER_SETS |
| ---------------------------- |
| |
| .. versionadded:: 3.24 |
| |
| Used to verify that all headers in a target's ``PUBLIC`` and ``INTERFACE`` |
| header sets can be included on their own. |
| |
| When this property is set to true, and the target is an object library, static |
| library, shared library, interface library, or executable with exports enabled, |
| and the target has one or more ``PUBLIC`` or ``INTERFACE`` header sets, an |
| object library target named ``<target_name>_verify_interface_header_sets`` is |
| created. This verification target has one source file per header in the |
| ``PUBLIC`` and ``INTERFACE`` header sets. Each source file only includes its |
| associated header file. The verification target links against the original |
| target to get all of its usage requirements. The verification target has its |
| :prop_tgt:`EXCLUDE_FROM_ALL` and :prop_tgt:`DISABLE_PRECOMPILE_HEADERS` |
| properties set to true, and its :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTORCC`, |
| :prop_tgt:`AUTOUIC`, and :prop_tgt:`UNITY_BUILD` properties set to false. |
| |
| If the header's :prop_sf:`LANGUAGE` property is set, the value of that property |
| is used to determine the language with which to compile the header file. |
| Otherwise, if the target has any C++ sources, the header is compiled as C++. |
| Otherwise, if the target has any C sources, the header is compiled as C. |
| Otherwise, if C++ is enabled globally, the header is compiled as C++. |
| Otherwise, if C is enabled globally, the header is compiled as C. Otherwise, |
| the header file is not compiled. |
| |
| If the header's :prop_sf:`SKIP_LINTING` property is set to true, the file is |
| not compiled. |
| |
| If any verification targets are created, a top-level target called |
| ``all_verify_interface_header_sets`` is created which depends on all |
| verification targets. |
| |
| This property is initialized by the value of the |
| :variable:`CMAKE_VERIFY_INTERFACE_HEADER_SETS` variable if it is set when |
| a target is created. |
| |
| If the project wishes to control which header sets are verified by this |
| property, it can set :prop_tgt:`INTERFACE_HEADER_SETS_TO_VERIFY`. |
