+define_property
+---------------
+
+Define and document custom properties.
+
+::
+
+ define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
+ TEST | VARIABLE | CACHED_VARIABLE>
+ PROPERTY <name> [INHERITED]
+ BRIEF_DOCS <brief-doc> [docs...]
+ FULL_DOCS <full-doc> [docs...])
+
+Define one property in a scope for use with the set_property and
+get_property commands. This is primarily useful to associate
+documentation with property names that may be retrieved with the
+get_property command. The first argument determines the kind of scope
+in which the property should be used. It must be one of the
+following:
+
+::
+
+ GLOBAL = associated with the global namespace
+ DIRECTORY = associated with one directory
+ TARGET = associated with one target
+ SOURCE = associated with one source file
+ TEST = associated with a test named with add_test
+ VARIABLE = documents a CMake language variable
+ CACHED_VARIABLE = documents a CMake cache variable
+
+Note that unlike set_property and get_property no actual scope needs
+to be given; only the kind of scope is important.
+
+The required PROPERTY option is immediately followed by the name of
+the property being defined.
+
+If the INHERITED option then the get_property command will chain up to
+the next higher scope when the requested property is not set in the
+scope given to the command. DIRECTORY scope chains to GLOBAL.
+TARGET, SOURCE, and TEST chain to DIRECTORY.
+
+The BRIEF_DOCS and FULL_DOCS options are followed by strings to be
+associated with the property as its brief and full documentation.
+Corresponding options to the get_property command will retrieve the
+documentation.
