# get_directory_property

Get a property of `DIRECTORY` scope.

    get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)

Stores a property of directory scope in the named `<variable>`.

The `DIRECTORY` argument specifies another directory from which to retrieve the property value instead of the current directory. It may reference either a source directory, or since CMake 3.19, a binary directory. Relative paths are treated as relative to the current source directory. CMake must already know about the directory, either by having added it through a call to `add_subdirectory()` or being the top level directory.

If the property is not defined for the nominated directory scope, an empty string is returned. In the case of `INHERITED` properties, if the property is not found for the nominated directory scope, the search will chain to a parent scope as described for the `define_property()` command.

    get_directory_property(<variable> [DIRECTORY <dir>]
                           DEFINITION <var-name>)

Get a variable definition from a directory. This form is useful to get a variable definition from another directory.
