set_property() has APPEND, which creates a list. E.g. when
appending to COMPILE_FLAGS a string is needed, not a list.
With the APPEND_STRING option the value is append as string,
not as list.

This adds the CACHE option to set_property and get_property commands.
This allows full control over cache entry information, so advanced users
can tweak their project cache as desired. The set_property command
allows only pre-defined CACHE properties to be set since others would
not persist anyway.
