define_property

---------------
|

|
|

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.
