SUBDIRECTORIES
|
||||
--------------
|
||||
|
||||
This read-only directory property contains a
|
||||
:ref:`;-list <CMake Language Lists>` of subdirectories processed so far by
|
||||
the :command:`add_subdirectory` or :command:`subdirs` commands. Each entry is
|
||||
the absolute path to the source directory (containing the ``CMakeLists.txt``
|
||||
file). This is suitable to pass to the :command:`get_property` command
|
||||
``DIRECTORY`` option.
|
||||
|
||||
.. note::
|
||||
|
||||
The :command:`subdirs` command does not process its arguments until
|
||||
after the calling directory is fully processed. Therefore looking
|
||||
up this property in the current directory will not see them.
