VERIFY_INTERFACE_HEADER_SETS

VERIFY_INTERFACE_HEADER_SETS

.. versionadded:: 3.24

.. versionchanged:: 4.4 OBJC and OBJCXX languages are now supported in addition to C and CXX.

Used to verify that all headers in a target's PUBLIC and INTERFACE header sets can be included on their own.

.. versionchanged:: 4.4 Previously, the verification target was only created when the target had at least one matching header. Now it is always created when the property is enabled.

When this property is set to true, and the target is an object library, static library, shared library, interface library, or executable (subject to policy :policy:CMP0209), an object library target named <target_name>_verify_interface_header_sets is created. This verification target has one source file per header in the target's PUBLIC and INTERFACE header sets. Each source file only includes its associated header file. If the target has no matching header sets, a utility target is created instead so that the target name always exists for build system dependencies. The verification target links against the original target to get all of its usage requirements.
