In CMake I want to get all property names that are set for a target.
In How to print all the properties of a target in cmake? they use cmake --help-property-list to list a predefined set.
But if you have a target that defines other properties how can I know which are they?
For example
set_target_properties(some_target PROPERTIES some_custom_property prop_val)
How can I get all such properties? I am looking for something like
get_target_property_names(some_target property_names)
