Try GET_DIRECTORY_PROPERTY with VARIABLES -- it should give you a list of variables for that directory. It will only be accurate after the ADD_SUBDIRECTORY for the given directory...<br><br>The presence or absence of the variable in question should give you the "defined-ness" of it... As long as you can guarantee directory A gets added first...
<br><br>C:\>cmake --help-command GET_DIRECTORY_PROPERTY<br>cmake version 2.4-patch 5<br> GET_DIRECTORY_PROPERTY<br> Get a property of the directory.<br><br> GET_DIRECTORY_PROPERTY(VAR [DIRECTORY dir] property)
<br><br> Get a property from the Directory. The value of the property is<br> stored in the variable VAR. If the property is not found, CMake will<br> report an error. The properties include: VARIABLES, CACHE_VARIABLES,
<br> COMMANDS, MACROS, INCLUDE_DIRECTORIES, LINK_DIRECTORIES, DEFINITIONS,<br> INCLUDE_REGULAR_EXPRESSION, LISTFILE_STACK, PARENT_DIRECTORY, and<br> DEFINITION varname. If the DIRECTORY argument is provided then the
<br> property of the provided directory will be retrieved instead of the<br> current directory. You can only get properties of a directory during<br> or after it has been traversed by cmake.<br><br>HTH,
