.. versionadded:: 3.29

More read-only target properties now error when trying to set them.

The :command:set_target_properties and :command:set_property commands are intended to error out on all read-only properties. However, CMake 3.28 and below only did this for the following properties:

:prop_tgt:HEADER_SETS
:prop_tgt:INTERFACE_HEADER_SETS
:prop_tgt:IMPORTED_GLOBAL
:prop_tgt:MANUALLY_ADDED_DEPENDENCIES
:prop_tgt:NAME
:prop_tgt:TYPE

This policy enforces the read-only nature of the following target properties:

:prop_tgt:ALIAS_GLOBAL
:prop_tgt:BINARY_DIR
:prop_tgt:CXX_MODULE_SETS
:prop_tgt:IMPORTED
:prop_tgt:INTERFACE_CXX_MODULE_SETS
:prop_tgt:LOCATION
:prop_tgt:LOCATION_<CONFIG>
:prop_tgt:SOURCE_DIR

The OLD behavior for this policy is to only error out for the properties :prop_tgt:MANUALLY_ADDED_DEPENDENCIES, :prop_tgt:NAME, and :prop_tgt:TYPE. The NEW behavior for this policy is to error out on all target properties that are documented as read-only.
