.. versionadded:: 4.3
Used to verify that all headers in a target's PUBLIC and PRIVATE
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, module library, interface library, or executable, and
the target has one or more PUBLIC or PRIVATE header sets, an object
library target named <target_name>_verify_private_header_sets is created.
This verification target has one source file per header in the PUBLIC and
PRIVATE header sets. Each source file only includes its associated header
file.
Properties affecting compilation are copied from the original target to the
verification target so that the headers will be interpreted the same way by
the compiler as when compiling the original target's sources. There are some
caveats with this approach. It cannot replicate the same conditions if any
of those properties or properties inherited through build requirements from
transitive dependencies contain
:ref:target-dependent generator expressions <Target-Dependent Expressions>
that do not specify the target for the expansion. Such expressions can expand
to different contents depending on the target they are being used on.
