I must admit I did not read your previous mail entirely but
did you notice that:
get_directory_property
Get a property of DIRECTORY scope.
[...]
The specified directory must have already been
traversed by CMake.
That is if the parent is retrieving daugther directory property BEFORE
the daughter was traversed then you won't get anything.
As far as I understand "add_subdirectory" doc, the subdirectory are traversed
"in-depth" first since
"The CMakeLists.txt file in the specified source
directory will be processed immediately by CMake before processing in
the current input file continues beyond this command."
so if want to get_directory_property from a daughter dir then you
ensure that add_subdirectory to the target dir appear before
get_directory_property.
Is it the case in your example?
Do you have a small example which exhibit the "get_directory_property" issue?
