#  GET_DIRECTORY_PROPERTY: Get a property of the directory.

  GET_DIRECTORY_PROPERTY(VAR [DIRECTORY dir] property)

Get a property from the Directory. The value of the property is stored 
in the variable VAR. If the property is not found, CMake will report an 
error. The properties include: VARIABLES, CACHE_VARIABLES, COMMANDS, 
MACROS, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, DEFINITIONS, 
INCLUDE_REGULAR_EXPRESSION, LISTFILE_STACK, PARENT_DIRECTORY, and 
DEFINITION varname. If the DIRECTORY argument is provided then the 
property of the provided directory will be retrieved instead of the 
current directory. You can only get properties of a directory during or 
after it has been traversed by cmake.
